05 636.. brake fluid expanding, locking brakes?
had this problem after i had the bike sitting in the winter last year and slowly tried to combat it and fix it but nothing has helped.
Whenever its hot outside or the bike is sitting idle getting warm, my front brake likes to get tighter on me. For instance, it normally has a small ammount of "give" before the brake activates, but that ammount gets smaller as the bike gets warmer. today i came home from school (hot day) and my brake fluid had expanded so much that the brake was slightly locked. could still move the bike but barely. whenever this occurs i hold the brake in and open the bleed valve on master cylinder to relieve pressure. (useful piece of information?) had this problem about 3 months ago, except it happened while i was riding. front brakes locked at about 5mph and bucked me off.. WHAT IS THIS PROBLEM?! replaced the brake lines and master cylinder, maybe its the calipers?
