Its amazing how fast you can make a decsion (when you really have to), and its circumstances like this that makes you glad that you have chosen good protective gear thats in good condition when you have to make one like this at a couple of hundred clicks.

In my case Human error was to blame (me), after being in a rush to change out some brakepads - and not finishing the job properly...... NOTE: it will NEVER happen again :-)

Any other OMG moments to share ?

Similar story...after just joining the Red Devil Race team Graham and myself went to Manfeild for one of the last rounds of the winter series. On the way down we were discussing how I had to begin to 'let go' of the mechanical jobs of prepping the bike and trusting my mechanics to do the job correctly (Ie Domini and Graham). First practice qualifying was wet so we needed to change wheels to wets, I did the rear and graham did my front (Domini was not with us as she had to work back in Auckland). He never checked the brake grub screws because he never loosened them...little did he know I (being a dumbarse) had not fully completed putting the pads in back at home and had left the grub screws loose as I was going to change the pads again when I got to the track...I forgot all about this.

First lap was fine, second lap I was just starting to wind up my speed as it was the first 'timed' lap for qualifying. I entered the final sweeper 'Dunlop corner' and applied the front brakes...they grabbed then instantly let go again! It was wet as I said so I began pumping my rear brake to swing the rear out as I entered the corner wayyyyyyyyyyyy too fast! I remember looking at the tires and thinking that they would hurt...readjusting my vision to the gravel trap and headed towards that. Somehow I managed to get the bike turned just enough to avoid a perpendicular impact into the tires and lowsided on purpose into the gravel. Broke a couple of ribs and the bike was pretty much undamaged. I fixed the bike up and raced the remainder of the day from the back of the grid as I didn't post a qualifying time. I was very fortunate to get away with that fopar relatively unscathed. Let me say, this has never happened again....and in fact had Domini been there on that day it wouldn't of happened either as she meticulously cheaks all the bolts/screws on the brakes all the time... This goes to show, when systems change in the pits you need to be very wary of ensuring everyone knows who is doing what. This is proof of the saying "Whatever doesn't kill you makes you stronger" I guess :sweatdrop

Both of those are why I've missed races. I refuse to rush doing anything on the bike and with certain areas, like the brakes, I never leave anything half done up. Everything is either off the bike or fully done.

There are times when it has to be done though so I'll do something like put a cable tie on the brake lever or just take the brake lever off. That way it's pretty obvious things aren't ready to go so everything gets checked.

One thing I'm going to have to get into the habit of is giving the lever a bit of a squeeze half way down straights just in case a head shake has pushed the pistons back.

and there was also the Nick Cole/brake lever incident!

[DEATH_INC.]

The last trackday I did I had a brake caliper bolt drop out...it let the caliper move enough that it had no brakes heading into a corner....lucky there was an escape road available.... still don't know why it fell out....the others were all tight.
I also remember a BRM trackday when a guy on a ZX7 had his front brake lever fall off going into the sweeper a Taupo a few years back....

Casey Stoner at Motegi last year was a good example shake, pump and run off...

Rhys holmes lost his front brake lever at Austins corner at HD in the Nationals, poor barstard didn't find out till braking for the hairpin was an ugly bin if i've ever seen one, also i saw johhny hepburn bail down the back straight at gisborne when he lost a front brake pad, they'd parked a truck there to stop spectators watching from outside which added to his 'pump and jump' decision.

also remember seeing chris haldane up on the inside of Bubbles Grey on the front straight at PUKE and snapped off his front brake lever...
no crash but one over tightened Sphincter there and a very quick said prayer i'm sure

not even fun to watch

If I ever leave a job unfinished esp if it involves the engine fluids or the braking systems I write a note on a piece of duct tape and stick it on the gas tank or the dash so as to remind myself or the person needing the info to avoid such problems.
Touch wood so far so good

[WRT]

The term should be "pump, dump and jump" cause loosing brakes in a race situation would be enough for anyone to crap their pants.

Then theres bbq or jump.

Robert Holden had a moment at ruapuna on a 916 Duke burnt one of his eyebrows off and all.

Back in the 90,s at Donington UK i had the brake lever fall off on my GSXR600 along the straight under the dunlop bridge...LUCKILY we were using the club circuit so instead of flicking left/right and heading down to melbourne loop we flicked right/left onto pit straight. So afer realising that the back brake wasnt gona do it i headed towards the melborne loop in the opposite direction to normal....... turns out i had forgotten to put the lock bolt under the pivot bolt.
Also saw a rider take another riders brake lever off again at Donington this time at carousel....... the rider was heading down craner curves (very scary) with no front brake towards old hairpin........... he realised and saved it without actually falling off....... did a whole lot of grasstracking.

When i was running 3 bikes at Ruapuna and racing....... i left changing a front wheel to owner of our current SV650....... he left one caliper bolt loose and it swung out and rubbed a nice groove in the rim!!! luckily he thought something was wrong and pitted..... ironically he had done the brake disc bolts SO tight i had to use an impact driver to loosen them..!

Most scary was one Sunday morning ...... we had been out for an early morning high speed blast around the english countyside.... had just witness my mate on his GSXR1100 pull 100mph+ mono,s down the local bypass etc etc....... we were almost home when i was riding beside him and noticed that the rear wheel spindle/axle was about 30mm out of the swingarm...... i stopped him and he admitted he had removed the back wheel the previous day......... the nut/washer was gone and the axle was working its way out. We pushed it back in and i rode the last mile or so very slowly with me riding along with my foot on his swingarm stopping the bolt from coming out. Phew lucky escape.

turns out i had forgotten to put the lock bolt under the pivot bolt.


Because of that fear, where I have a hollow pivot bolt (some brembo ones are)I run a tie wrap through the bolt and around the outside of the master cylinder so if the ut falls off a) the tie wrap catches it and b) the bolt can't jump out.

I've arrived at Barrel 51 doing the out brake up the inside when the level collapsed against the bar as the brake fluid boiled ( no loss of fluid, good fluid too, we think pad drag caused heat soak) and it's amazing how it seemed to accelerate....

Never ever thought I would be able to step off a moving motorcycle from my own decision making. Is soooooooooo easy when you have to......!

[roadracingoldfart]

Funny as it is i was telling this story at work on Thursday !!!!.
Mid 90s on a CBR600 and just snicked 6th , back straight of Manfeild, slight fingerhold ready on the brake lever ......... ummm what lever ??.
I didnt crash but only because i was suctioned to the seat by my arsehole movement and just aimed at the apex and held on. Turned out the lever had actually broken at the pivot point.
Scared the hell out of me.
Also had a loose handlebar in an endurance race and after 30 mins on the track i fell off coming into the pits cause the cones to slow us made the bar turn and jamb against the tank lol.

First at taupo, VMCC round a few years back: On my Z, at t1 my left handle bar kinda moved as i went into T6, after T8 i found out the bolt holding it into the fork mount had broke, thinking right time to pull in, I looked back saw a then ORANGE biked Deano, put my head down and kept'd force into the fork on my left hand, was interesting to say the least.

Second at Wanags, going through the cemetery S's, something hit my right knee, into Rob h, hit the brakes, well reached for them, when you don't get anything with your right hand you do sh*t ya pants. the lock nut had come off then the pin unthreaded so the lever plain fell out......Ran through the corner changing down and locking up the back end terribly. had to retire from that one.

Last was T1 at manny, hit the front brakes, and hit a false neutral, got target fixated on it then was off the track still carrying a good 100ks, grass offered nothing, when i hit the gravel i noticed the welcoming tire wall looming. So i had to abandon ship, choosing to hit the wall without the bike, it was a surreal experience. Everything slowed down and i remember every part of the decision......"hmmmm i ain't going to stop, thing i should get off.....right side seems good.......sorry girl your one your own" i literally just rolled off to the right. The bike and I hit the wall at the same time but happily apart. Gravel rashed y helmet, the bike was actually dam good, but i buckled a front brake rotor in the gravel pit ( glen you actually helped me work that one out )

Id recommend it again....;)

[ellipsis]

....I know how fast I can REALLY get through the bales and onto the start/finish straight at Greymouth now, after a low side out of the hairpin 400 meters back...jumping back on, trying to make the lost place back, I was giving it all, quick dab on the front brake...no lever......

[gatch]

At puke last year. Having gone through turn one and just about to brake for the left riiight onto the back straight. The carbs were iced over and jammed wide open. Decided on going over the grass, pushed on the inside bar and it turned on the fork tube :crazy:

Too fast to take the left I went over the grass, got turned and just kissed the back wall. No injuries or further damage, except for a change of undies.
