I’ve been having a problem with my front disk brake, which I thought I had solved. Apparently not. The issue is the front brake not releasing. It first happened on the road, and the subsequent overheating ruined the caliper. I found a nice used unit, and installed new stainless pistons, new seals, and of course, new fluid. Everything seemed to be working okay, though honestly, I just rode it a few miles.
Today, I took the bike out after having sat for a few months. Just rolling out of the garage, the brake would not release again. Lots of play in the lever. In order to get it back in the garage, I had to open the bleed screw, which released the brake, though the lever is still sloppy.
I figure I have a master cylinder problem, but having never been inside one, I’m not sure where to start. Back in 2010, I had the master cylinder overhauled and re-sleeved by Fair Spares. Also, the bike has a stainless braided line that is about 35 years old. I’ve heard that on old cars, sometimes a brake hose will collapse internally and create this issue. Any ideas as to where to start would be appreciated.
Thanks!
