Rear Caliper Binding

[Guest]

I've been down for a few weeks awaiting a good time to address my bike's latest issue. I got to it yesterday, with the idea of taking the caliper apart, piston out, cleaning it and all that, but while I was breaking the bolts loose, with the brake line disconnected, it suddenly burped out some crud and let go of the disc.

I decided to tighten everything back up and try flushing it. It took me a bit to get any fluid moving at first - I ended up submerging the banjo thing in fluid and working the pedal several dozen times, and it finally started flowing. The stuff that came out of the bleeder port was naaasty brown.

That seems to have fixed the problem, at least for now.

I went ahead and flushed out the fronts today. The initial stuff that came out was rusty brown, but not as bad as the rear.

I guess I've been fortunate in not having to deal with anything like that in years. I flushed the front brake fluid on my first bike because it was visibly dirty, but the rest haven't given me any trouble.

You would still do well to tear down the calipers and master cylinders for a good thorough cleaning and inspection. You can (and should) flush the brake fluid every two years as a preventative measure but it's no substitute for a teardown when you know there's crud in there.

Sounds like you are a Darwin award winner in training. When the system is full of crud like that the only way to properly, and safely, fix the bike is by tearing down the full system to clean everything out and replacing the brake lines.

Yeah, I figured as much. Worked as good as ever today though.

Lol. Too late. I've already reproduced... many times over . That's one reason I can't afford a newer bike with clean brake systems .

Well, take care of things proper, or your kids might have to grow up without a Dad.
