My bike tried to kill me today

[98tls]

If sum-cunt is riding their motorbike without even being aware of a sticky rear brake that's gonna heat up and lock the pads solid then they shouldn't even be riding motorcycles. Yet another example of greenhorns on bikes trusting every other cunt to keep themselves alive. Wake the fuck up and take responsibility for what the fuck you're doing. Take no fucken notice of the posturing drip-heads like the mouthy crashfromback spouting shit about how they pass everything in sight, blow-arses who talk that are living in a little bubble of self-importance. Probably spent his childhood being ignored by the other kids and getting bullied but found that riding motorcycles made him feel like a special person... Again, ignore all the sewerage from these wankers and wise the fuck up, use common fucken sense and check your fucken bike over for faults before you start charging around the fucken roads

Aint P wonderful.Be warned fella that sack you wake up with in your mouth tommorow morning isnt the remains of last nights enchilada its your boyfriends sack,dont bite.

isn't that what novices are tought at track days?

I suggest it is hazardous to think that way. I suggest the rider should be utterly flexible at all times, with no fixation on any line.

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.

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.

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.

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.

If it did, then that is a failure mode I haven't seen. Normally water gets in through the boot and corrosion jams the piston in the cylinder just like the one on my workbench right now.

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.

There's only two self important blow arses so far in this thread.

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.

Quoting myself once again ;

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.

The fact that 'you' have to do that, and more than once, tells us that the master cylinder/s as fitted by Hyobag are a load of crap. Much like the rest of the bike/s, really...

Yep. Can't imagine that many learner riders on 250s would have the mechanical skills and knowlege required to fix/check for these sort of problems on the Hyosungs.

Plus one. Sounds dodgy as, thank fcuk they don't make off road bikes.

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?
