Ok all you knowledgeable people out there, this is the story. Riding along minding my own business [moto] apply rear brake in traffic and pedal is all soft like nothing is happening. Assumption correct, there is nothing happening.
Stop, get off, look for leaks, find none, ride home, start pulling stuff to bits.
Brake pads are worn to limits so purchase new ones and install (might as well start with the easy stuff) but still no pedal. I think this might be the case but hope it isn't. Attempt to bleed brakes but no fluid comes through when pushing pedal. Remove master cylinder.
Remove piston from master cylinder with some difficulty. It's getting stuck in the white plastic (nylon, teflon, whatever) sleeve.
More questions...
Should the piston move freely in the sleeve? It's almost like the spring can't push the piston back far enough.
Can I change the sleeve easily?
There is some corrosion evident around the circlip. Is it possible that corrosion has put the sleeve out of shape and caused the piston to get stuck?
Thanks in anticipation of your advice.
Cheers,
Rob
