My bike tried to kill me today

[trailblazer]

well i decided to go out for a bit of a ride before i went around the east coast tomorrow but that plan came to a screaching holt today. I was out doing my usual loop which is just over a 100ks and 40 odd ks into the ride i pulled out to pass 2 cars that were doing 85ks and when i pulled back in i started to brake for a nice tight but easy left hand corner that was all fine but while i was leaned over in the corner i just feathered my rear brake a bit just to keep the bike on line and all of a sudden there was a loud bang and all i knew was my bike stepped out and threw me into the air. Im guessing it was what a high side feels like but i managed to hold the bike and hit my nuts on the tank when i landed but the bike just stopped dead in its tracks and i had cars going in all directions trying to avoid me. all i can say is well done guys that can't have been easy. Well it appears that the loud bang and shudder i felt was my rear brake siezing solid. The cage drivers stopped to see if i was ok and told me that i had put on a pretty good show for them but they thought they were going to smoke me and had only just missed hiiting my bike. Now it appears everytime i want to go on or attemped to go on a long trip my bike breaks down. Well i have had enough now and i want hyosung to do something because my bike has spent most of its time in the shop getting warranty work done but i have told them before and i will be telling them again my bike is not safe and they need to do something other than just patching it again.

Mate you buy a hyosung knowing full well this is gonna happen!

Glad you're ok, sounds like a bloody scary incident to be in! Time for a different bike?

[Mom]

How long have you had this death trap? It needs to be fit for purpose, and the purpose of riding a bike is not to fight a rear wheel lock up mid corner. Thank goodness you manged to ride it out.

[trailblazer]

prior to this it has just been dying when hot and hard to start when hot and the speedo has been false but never anything like this before it just knocked my confidance and now that was just dangerous and i dont even ride it hard or fast.

[Katman]

You sure a stone didn't flick up in between your chain and rear sprocket?

Closely inspect your chain for any damage to it's links.

[trailblazer]

I have had it for 18months but it has a 2 year factory warranty. i have just spoken to our family lawyer and they said i should be able to get a refund as bike is still under warranty and hasnt even done 6000ks. I wont be buying another one thats for sure.

[trailblazer]

nope we had to release all preasure out of the rear caliper to get the wheel free again but it still rubbed a bit and i had to keep stopping to let the rear disc cool down so i didnt do any further damage

[Ocean1]

Was the back brake still locked when you finished trying to crash?

Is it still locked now?


Edit: Nevermind, you answered it.

[Katman]

There is a tiny hole in the bore of the master cylinder that allows the brake fluid pressure to bleed off. It is relatively easy for this hole to become blocked by a little piece of shit.

I wouldn't expect that to happen on a bike with 6000km. another possibility is that one or more of the rear wheel bearings has collapsed although again I wouldn’t expect that at 6000km, unless a spacer has been left out of the rear axle at some stage.

[trailblazer]

what ever it was it made a very loud bang and it all happened in what felt like a second. I hope i never have to experiance that again.

Perhaps one of the locator pins came loose and got the pad wedged in between the caliper body and the disc.

I wouldn't fuck with it, just tell the dealer what happened and let them sort it.

[ClutchITUP]

who had the rear wheel off last? spacer issuse? ie wheel not running true

[trailblazer]

bike shop had the wheel off about 1000ks ago if that to put new tyres on. I havn't had any issues with it until today but im no expert so i guess the bike shop will sort it tomorrow.

[Ronin]

bike shop had the wheel off about 1000ks ago if that to put new tyres on. I havn't had any issues with it until today but im no expert so i guess the bike shop will sort it tomorrow.

So it had new tires fitted at 5000k's? Not a litre bike in disguise is it?

[trailblazer]

nope i hated the shinko's that come new with the bike. they were dangerous in the wet and i never felt comfortable riding in the rain so i decided for peace of mind and my safty i would put new tyres on it.

Im not planning on fucking with it im going to put it on a trailer in the morning and take it into the dealer.

[Wannabiker]

I might suggest someone has adjusted the rear brake lever pushrod too much and the piston is not uncovering the compensating port in the master cylinder. Fluid becomes trapped in a closed circuit, overheats and locks the brakes. :(

You are hardly qualified to offer advice on braking systems.

(Don't make me post a link to the thread).

[trailblazer]

i dont think my brakes have been worked on from new. The pads have more than half of there pad left. Unless the dealer has adjusted them in the services they havn't been touched by me or the dealer. Shit at the last service the bike had only done 5000ks so they shouldn't have been touched. My 2c

I'm surprised some twat hasn't said it was your fault for not anticipating it.

The same twat might well suggest that this is exactly why a safety buffer should be incorporated into your riding manner.

A safety buffer for the rear locking up when giving it a slight nudge? If I'm riding and have inspected/tested brakes before beginning the ride that should not bloody happen which means no safety buffer for that event. That would be like creating a safety buffer for the throttle jamming open all of a sudden, or the screen flying off and hitting you in the face even though you check the throttle cable and the screen's secure... no one sits there expecting that to happen.

[trailblazer]

I always ride with the theory that I don't know what is around the next corner or on the corner (animal,gravel,diesal or whatever) that im about to turn into but i would never have thought my rear brake would seize mid corner for no reason at all. That is something that i will always watch for from now on though.

[Usarka]

I'm all for not riding at 100% on the road in case shit like this happens. But the reality is you cannot plan for everything all the time and in a case like this it could easily go either way depending on a number of factors (experience, severity of failure, other distractions, and sometimes plain dumb luck to name a few).

I'm glad this went the right way, and I'm glad we don't have to put up with people saying that it serves you right.

[Katman]

no one sits there expecting that to happen.

Maybe not, but you're stupid if you don't allow for the possibility of the unexpected.

I didn't even really give it a nudge all i was doing was really just applying slight preasure so it wasn't like it was a short sharp stab of the brake. That i would expect the bike to do something weird.

If you really need to ride at 3 miles an hour to sufficiently allow for the unexpected, find another form of transport.

I do ride with allowances for something to happen that is why I don't ride hard if i wanted to do that i would go to a race track. I think i did well to hold on to the bike when it tried to throw me. And the cars behind did well not to hit me so because of those 3 things im here tonight with my family and not in a hospital with serious injuries like so many other reports that we read on here.

Could have been worse....could have been the front brake.

And Katman...I'm a very conservative rider but I'm not sure I'd be able to keep rubber side down if my rear brake locked up mid-corner.

[Katman]

The lack of comprehension on this site is astounding.

For anyone to sit here and say that they have got it sorted and won't crash after an unexpected rear lockup is deluding themselves.

It's called 'Not riding at 10/10ths'.

You're not only full of shit...you're delusional. Don't you think there'd be a lot of off road riders getting thrown over the bars if a lil old stone in the chain/rear sprocket would lock the rear wheel? A BOULDER maybe...but with the weight and momentum of a road bike...ain't no 'stone' gonna lock the rear wheel. Don't you own a motorcycle repair shop? Maybe if a stone got caught above the rear brake lever when it was depressed...stopping it returning, hence getting everything so hot it eventually locks the wheel...

[Woodman]

My god!!!! its a revelation. :tugger:

Fcuk me I'm going to bed.

[Katman]

Methinks you're the delusional one.

Dirt riders deal with an unrotating rear wheel all the time.

[Crasherfromwayback]

Shows what you know (or actually don't have a fucking clue about) then. You seriously think if a person is ripping along on a dirt bike, and out of the blue has the rear wheel lock they won't get pitched over the bars? I've been riding & racing dirt bikes for 34 years and have NEVER had a rear wheel lock due to that. Don't know anyone that has either. A chain and sprocket will either spit out, or crush a stone at speed.

[scracha]

Not sure what I didn't comprehend but there you go.

He obviously had taken your advice and wasn't riding at 10/10ths, as he didn't crash.

Brake seizure is very unlikely to happen. In fact, I've never heard of another rider having brakes seize up and lock like this*. Riding is a calculated risk; there's no point in spending your life riding for risks that are very unlikely to happen. I ride at about 5/10ths as risks for me include gravel, tar bleed, cars and animals on the road.

Brake siezure or sudden front tyre blowout MID BEND are in the "extremely fuckin unlikely" category for me and therefore I don't ride at 1/10th (as I'd have to) so I'd probably crash if this happened mid-bend. However, because I'm not riding at 10/10ths I'd have a much better chance of surviving.

By your logic I should get a vasectomy and wear 2 condoms.

As for stone in rear sprocket.....I've never heard of this either. The stone would just get chewed up.


* I've had sticky front calipers and the disks heat up and you kinda notice it very quickly.

i started to brake for a nice tight but easy left hand corner that was all fine but while i was leaned over in the corner i just feathered my rear brake a bit just to keep the bike on line :rofl::rofl:Reads like a fucking Tui ad.Nice work.Think my kid did that on his playstation the other night,thankfully he to survived.

Funnily enough, the tosser has red repped me saying " read the thread...the post about the brakes locking up was after mine" (or some such drivel). Funny...because I don't care what was said after Katmans post...because I was still laughing too hard at his.

Fricken hyosung build some rubbish machines. To be fair, I was out riding with a bloke on a brand new Aprilia that did exactly the same thing, rear caliper just seized and that was it. Had to release pressure via brake fluid nipple to get it going again.

Hope you get money back ok.

You have the right attitude to be out and about on two wheels, but please dont ride taking into account your rear brakes are going to seize up mid corner, every corner you ride around. What a joyless riding experience.

Get rid of the crappy bike and enjoy two wheels :yes: Oh, keep the attitude though eh?

[CookMySock]

The rear brake locking up is a known fault. I've rebuilt perhaps five of them.

It's an easy fix and will probably cost you nothing. Bring it over if you want, and I'll show you how to fix it and modify it so it can't happen again. If it needs seals, I have a source for those as well.

Hyosung owners PLEASE CHECK your rear brake pedal. If it's rock hard and the bike is hard to push then GET IT FIXED or take the caliper off and bring it to me and I'll show you how.

I seriously hope you're not suggesting that you shouldn't allow for unexpected occurances while you're riding Anne. I gave you far greater credit than that.

The reason that many top race drivers dab their brake pedal before actually braking for a corner is not to remind them where the brake pedal is - it's to ensure that the brake pedal is actually working.

[Oblivion]

Wow. Did we return with clean undies from this Journey? :rofl:

Reading all this puts some doubt in my mind that I should be using the brakes at all during a turn. I usually just lay off the throttle a bit, then just lean round the turn. Engine braking is enough for me I think. With tight turns I brake beforehand (Obviously)

If it is a known fault then why havn't they got it sorted and had a recall on there bikes. One day it may just kill someone and then will they recall them. Its a bit late then though. My brakes have never given me any indication that something was wrong otherwise i wouldn't have been out there on the bike. Bike will be back in the shop in the morning as it is under warranty still so i dont want to fuck with it.

Wouldn't the warranty be void if there were obvious signs of mechanical tampering?

Or am I losing it? :blink:

glad youre ok mate. i went out for a jaunt today too after just fitting some new ebc sintered pads........wow.....hardly any pressure needed at all.

i must say i usually find that i rarely need to brake for corners on the road anyway as i tend not to rush in there as you never know whats round the other side.

i never use my rear brake in a corner, i 'may' try it and see how it feels. however, if ive misjudged the corner and find im running wide, i do as the superbike school peeps say to do and it works............drop your head and bodyweight forward and into the corner towards the mirror.tightens the corner up neee bother.

YIp brought brand new and have had it for nearly 18months of which time it has been back i think 6 times for faults that were covered uner the warranty. Bike has always been serviced at a dealer and in it 6000ks has had 3 services and is due to get its 4th due to the time between services not the milage. I don't know if i will have any luck but our family lawyer seems to think so and also suggested we mention target or fair go as threats before we have to take it to court.

I always ride with the theory that I don't know what is around the next corner or on the corner (animal,gravel,diesal or whatever) that im about to turn into .
That's a good theory. I always slow down when riding on back roads I've not ridden on before, especially since a lot of these roads aren't sign posted and so you have to watch your speed in case you come across a sharp corner over a crest for example.

Frankly mate and sorry if I offend you, you bought a piece of cheap Korean shit and these are the sorts of things happen when the components on the bike (such as the brakes) are cheaply made, low quality, low tolerance items assembled by 8 year old kids.
By chance is your rear brake hydraulic or cable actuated? That might sound like a silly question but it wouldn't surprise me if the Tiddlywinks used a cheapo cable operated caliper which could (probably) lead to cable binding or seizing issues causing your lock up.

[scracha]

Have you never watched footage (no pun intended) of the V8 drivers feet while they're racing?

V8 drivers do it because the vibration caused by their bumpety tracks/kerbs knocks the brake pistons back. The resulting fraction of a second's delay would cause them to crash because they're driving at 10/10ths. Hardly applicable for a road bike.

Maybe so. But even if the components on a Jap bike are outsourced to China, Korea or where ever, they will be made to a specified tolerance and will go thru a quality checking process and if they don't meet the given spec, they don't make it to the bike. I have seen Hyo's, Lonchins and other like makes and they are definitely sub Jap bike standard which is why they are cheaper. Lots of nasty looking rough castings and cheap pressed steel components you wouldn't see on a Japper.

Good to hear you didn't crash.

[Crasherfromwayback]

No worries Cocksuckerfromwayback.

Funny how that's the best you can come up with when sprung for talking utter shit.

Not so good at getting it back are you? By the way...dunno if you watch any racing, you probably consider it too dangerous even to watch...but if you do, you may've seen riders like Anthony Gobert, and Shinya Nakano getting pitched over the bars when the back wheel suddenly locked up. This, from ex 2 strokes racers who are always waiting for a siezure! Yet YOU...you could always catch it in time...because wait for it...yep...YOU'RE that good! You really should get hold of Repsol and tell 'em you should have Stoners ride. Don't forget to ask them to fit a stone guard to the rear sprocket though!

[p.dath]

Wow you are lucky to have made it. I don't think I could have held together a rear wheel lock up on a corner.

I did some searching, and it seems the rear brake issue is pretty common on your bike. I found this interesting post (go to the bottom to read it):
http://korider.com/index.php?action=printpage;topic=11639.0

Here is an excerpt from the official service bulletin from Hyosung USA

ALL GT250R AND GT650 S-R MODEL ARE SHIPPED WITH THE REAR BRAKE LEVER SET FOR THE STANDARD (NON S/R) POSITION.
THE LEVERS ON THESE MODELS NEEDS TO BE ADJUSTED AT P.D.I. TO A POSITION SUITABLE FOR A SPORT BIKE.

TO ADJUST LEVER

(1) LOOSEN THE LOCK NUT ON THREADED ADJUSTER ROD AT REAR OF PEDAL
(2) SCREW ROD IN TO CLEVIS PIECE UNTIL LEVER IS POINTING DOWN AT A 4:00 O-CLOCK POSITION SIMILAR
TO SHIFT LEVER.
SEE PHOTOS
(3) RETIGHTEN LOCK NUT
(4) REAR BRAKE LIGHT SWITCH MUST BE RE ADJUSTED FOR PROPER OPERATION

The lack of comprehension on this site is astounding.

Thanks KM, been a while since i read a thread front to back and just the same as the OP's refusal to roll over, yours impresses me !

Shame the Hyobag has fucked ya over this many times but as someone said, you bought it ! Good luck gettin ya money back and it's a shame no one got video footage of your near Highside (or you might have thought to grab names of witnesses to the incident), it would be nice to see such a precedent set in the courts, that would get the price of Hyobags rising (in a roundabout way)
Least you walked away and the bike hasn't blown up , just out of warranty (yet) Aye Gubb (and several others i have read about on here)

[Timmeh:P]

Glad to hear you are ok.

The first thing I ask, is why did you feel the need to "feather" the back brake??!? I can understand the logic if you are on a race track fanging it, but everyday riding there is just no point!

The back brake may still have seized if you had not touched it... But maybe, just maybe, if you had taken the corner without the need to "feather" the back break to "keep it in line" you might have completed the corner without incident.

[Elysium]

So it should be the bike shop or suppliers job to have this sorted before selling?

[scracha]

Surely in a safety critical situation (BRAKES) there'd have been a mandatory product recall? You can bet in 1st world countries where people can sue, this has been done.

[p.dath]

So it should be the bike shop or suppliers job to have this sorted before selling?

The bulletin says it is to be done at PDI (pre-delivery inspection), so at least prior to delivery to the customer.

[nosebleed]

... To be fair, I was out riding with a bloke on a brand new Aprilia that did exactly the same thing, rear caliper just seized and that was it. Had to release pressure via brake fluid nipple to get it going again.

Hope you get money back ok.

Yeah, theres been more than a couple of examples in the States. Usually arising from guys trying to combat the "lack of rear brake" issue that haunts the RSVR by over adjusting the actuating rod, as mentioned earlier in this thread.
Is your mate on a 'new' RSVR or RSV4? and who was the dealer? (you can PM me if you want).
I'm only curious about the dealer as I'm still not decided about who to deal with, with the demise of MEMC.

So it should be the bike shop or suppliers job to have this sorted before selling?There is nothing heinously wrong with the brake cylinder. If the rubber boot was pulled off and a slop of grease added the whole problem would be prevented. In any case, the problem is easily resolved in retrospect at almost no cost.

Since the rear brake will have been sticking for some time, I fail to see how the rider hasn't noticed it. If the rear brake was sticking, it behooves the rider not to stamp on it hard mid-corner lest the fucker bite you. Further to that, I understand touching any brake when using maximum angle of lean simply sacrifices said angle of lean. More than once I have discovered myself with a big handful of front brake mid-corner and after a reality-check decided it would be "um wise" to gently release it.

edit: I'm going to draw it to the attention of the local hyo dealer. Much hassle could be avoided etc for just one squirt with the greasegun.

This is a new rider, and they may not have noticed the rear brake sticking a little bit (if it even was sticking). The OP also said they applied light pressure, as opposed to stamping on it hard. Having said that, I think you'd have to be a bit brave stamping on the rear brake hard while cornering and lent over on a road - weather it had a fault or not.

[Wannabiker]

Any news of the bike from the dealer / service agent??

[trailblazer]

yip apparnatly hyosung have apparantly only had 2 or 3 cases of this reported to them so i guess they don't think its a major issue. Bike is getting rear brake rebuilt and rear wheel bearings getting checked at the dealer at the mo. the dealer has been realy good and have been trying to get this sorted for me and even gave me there shop harley to (suzuki dr200) to run around on until my bike is sorted. Still not convinced about my bike being sorted with all the issues so far but i gues we will see what happens as money is a bit tight right now so can't just go get a new bike just yet.

[Old Steve]

Whats this about a rear disc brake? New fangled technology. My GLORIA (Hyosung GV250) has a rear drum brake and as we can't get up to frightening speeds it's been perfectly adequate.

I remember when I was very new to riding, second or third ride, I went into a left hand corner and started to fade wide. I didn't know to look at the vanishing point or to lean more to tighten up my line around the corner, so I gently touched my rear brake thinking that at a slower speed I'd get around. All that did was set me upright and I went outside the curve to the right - luckily there was a wide painted median on which I came to a stop, but in a normal two lane road I'd have ended up on the other side.

Yep, you pretty much need to pick your line before you enter a corner, well for bikes like mine anyway. Not a good a good idea trying to re-adjust your line while already commited.

Surely you hauled on the front as well? It is the front brake that will stand the bike up - not the rear.
Use of the rear when cranked over risks locking the rear and/or flicking the back towards the outside like motards 'backing it in'. Worse case scenario is a lowside.

KM:

read your posts through this thread and while I see your general reasoning IMO you have your skew quite wrong.
Firstly lets be absolutely clear, you cannot be prepared for everything that could possibly happen on the road. The only way you could would be to not go on the road at all. Do you wear body armour every day as there is a miniscule chance you could encounter a gun-toting maniac (though more likely you may need protection from disgruntled kbers)? Do you wear all your bike gear while posting on KB?
I think you have to define a line between what is reasonable risk and what isn't. I personally don't like following rubbish trucks or vehicles carrying rubbish too closely as there could be debris flying off that could make my ability to control my bike difficult (plastic bag covering visor). However I think if you regularly maintain/look after a vehicle, particularly from new and within the warranty period, I think it should be more than reasonable to expect it to work exactly as per manufacturer's specifications, particularly considering the lifespan of the vehicle would be expected to be a lot more. If a part is failing while being duly maintained then the manufacturer needs to be reexamining the design of the part and/or assigned maintainence routine. One of my mates while riding on dirt had his handle bar mounts snap, I am not sure how one would ride to be prepared to control the bike if that happened.

[Ocean1]

I personally don't like following rubbish trucks or vehicles carrying rubbish too closely as there could be debris flying off that could make my ability to control my bike difficult (plastic bag covering visor).

Another thing to worry about when following trucks. I was doing just that one day when I noticed something sorta blinking in and out of view between the dual rear wheels. It took several seconds to occur to me what this might be and what it meant, in the meantime I'd rolled back a few yards and faded right a bit 'cause being there didn't feel good.

The blinky thing stopped blinking and started getting bigger and half a brick went past my left ear. It'd been stuck in between the tyres when he'd been on a demolition site and stayed there until motorway speeds eventually flung it out. That was years ago, but I've seen the blinky thing several times since, it's not that uncommon. If you see it then fuck off outa there, if you get a chance tell the driver too eh? it's fook'n dangerous.

My 'skew' is that riding at 10/10ths on the road is not allowing any safety buffer to be able to react to an unexpected occurance.

If you can't see the sense in that then I suppose that's your problem.

I am not sure what sort of safety buffer you could allow for any of the following happening:

- handle bar mounts snap (as mentioned above)
- pretty much anything to the front wheel - blowout on the front tyre (maybe not such a problem off road) while cornering or sudden front lockup at any time let alone spokes break or axle snaps.

I could probably think up some more but I think you get the idea, they're pretty much minimal chances but they could happen.

Yes riders do have a choice but far as I was tought (as in by people with years riding exprience) you should have worked out where you're line is before you enter said corner, not after you've gone into the corner. Obviously if a car is crossing centre line towards you for example, then yes you try to adjust your line and get out the way if you have time and space.

Correct me if I'm wrong here folks, but isn't that what novices are tought at track days?

Curiously, my daughters Comet 250 locked its' rear brake on today. Exactly the same problem - stuck master cylinder. I'm sure I rebuilt it. Will report back after pulling it apart tmw.

I wouldnt quite agree that a lowside is the worst case scenario. Locking the rear brake part way through a corner can be the start of several nasty scenarios. After initially starting a rear wheel slide, the back tyre often regains traction and flicks the rear in the opposite direction - potential highside (and probably what happened in this case). If rider is lucky enough to land back in the saddle (and it will have nothing to do with skill) it may not be the end of his problems because this could then be the start of a nasty tank slapper.
Sometimes you might be lucky enough to bring the slapper under control, but if it is violent enough, it will end in a trip over the bars.
I speak from personal experience in these various scenarios and in my experience, a lowside is one of the "better case" scenarios of a locked back wheel.
Much safer to stay well away from the back brake in corners unless you are a very skillful and experienced rider.

[SPP]

Correct me if I'm wrong here folks, but isn't that what novices are tought at track days?



Nah, even on a track you’ll need to adjust your line sometimes no doubt. The good trainers will show you how to do it without upsetting the bike e.g. a hook turn, or if early enough by checking roll on to quickly repoint the bike and roll back on… I’ve never heard anybody say it’s ok to use rear brake (or front brake either for that matter).

On the road.. well it's obvious

what the fuck are you on about. My rear brake was never sticking and heating up something broke in the rear caliper and caused the brake to seize on the parts that broke are on order. If my bike ever showed signs of anything wrong it has always been sorted before i ride same as my cars and my trials truck. And crash never said that he pass everything like some fuckwit that thinks he is on the local race track he just stated that he passes the cars in front when it is safe to do so. I guess you have never passed a car and just sit in the line of traffic then.

[CookMySock]

My rear brake was never sticking and heating up something broke in the rear caliper and caused the brake to seize on the parts that broke are on order.If it did, then that is a failure mode I haven't seen.

How does the water get in?? shit I have been riding my bike through rivers for about 4 years and it has never happened to me. in fact their is no corrosion there at all.
I think maybe the corrosion you see is because of the hydroscopic nature of the brake fluid.

Yea, I was being a bit simplistic. But use of the rear brake won't stand the bike up. Lots of us make light use or the rear brake (trail-braking) in corners, at times anyway, which can help control speed and line better than using the front, which requires more counter-steering to avoid standing the bike up.
In the case of a bike being cranked over in a corner, that suffers a total lock-up that can't release, a lowside is highly likely. That is what I meant by 'worse case scenario'.
You are right, each situation is different, and a lowside could lead to worse nasties, most of which will involve hitting something else. Uncontrollable fishtailing, tank slappers and/or high sides are very unlikely, unless the wheel locks up, then releases.

[CookMySock]

I stripped the master cylinder and the was full of rust and gunk. Cleaned it out, greased and reassembled and its mint. Total time 1 hour. Total cost $5 cleaning fluid, grease, and brake fluid.

[cowboyz]

The reason that many top race drivers dab their brake pedal before actually braking for a corner is not to remind them where the brake pedal is - it's to ensure that the brake pedal is actually working.


I often use a dab of rear brake to settle the bike going into a corner.


Have you never watched footage (no pun intended) of the V8 drivers feet while they're racing?



you often ride your bike on a public road like a V8 race driver in the middle of a race on a purpose built racetrack?
