Hi all On the way home today (on a GS500F) I had to brake pretty heavily, and the rear wheel locked up completely. The rear brake pedal felt like it was stuck down, and I had to step on it pretty hard to get it off again. Since then the rear wheel has been locking up on application of rear brake or downshifting, I think that the brake is stuck on?! Has anyone had this problem, or know how to fix it? Help please! Edit for more info - bike only has about 4,000kms on it, and rear tyre looks fine. No problems when cornering hard under steady throttle, but it did slip a bit when pulling out from a t-junction.
