As posted by neil748r Secondly, I know someone that this front brake locking has happened to. Unfortunately he wasn't so lucky, happened on track, front locked solid and spat him off at 80 + mph! The cause was something to do with a tiny little grub screw on the lever. It had either come out or worked loose and backed out/in, whatever, the result was as above. I think you have to remove the lever to find it. As posted by jools I've never owned anything later than a 2001 ST, but on the these bikes the brake and clutch lever have a large grub screw near the pivot. It looks for all the world as if you can use this to adjust the lever span but this is a mistake, because if you adjust it too far the master cylinder piston doesn't return far enough to let brake fluid return and the brakes effectively 'pump up' until they lock.
Since, somebody mentioned 'grub screw' earlier on in this thread could it be a similar problem?
i recently fitted a pair of adjustable levers to my 600SS just a simple job i thought until i had brake binding puzzled by this i saw grub screw and wound it out this relieved the problem of brake binding then i noticed the original ones have same grub screw but are araldited in place to stop tampering and vibration so i loctited the new ones in place --dont know wether this has any relevance to your brake problems saw the threads about the grub screw and thought id add my 2p's worth

Maybe Luigi was too busy having a fag one afternoon....
At the risk of sounding sexist (would I ever?!?), the visitors to the factory said that a lot of the assembly is done by wimmin. So perhaps Luigi was too busy to keep his eye on Mrs Luigi's work.
