Pison Siezed in Rear master Cylinder....

#1 (**permalink**) 07-02-2005

Does anyone know of any techniques to remove a siezed piston out of the rear master cylinder? I have the entire assembly to that point removed, just cannot get this piston out.

remove the parking brake and push on that pin sticking out. its part of the piston. and heat it up before you push on it.

No, not the rear Caliper... The rear master cylinder. That is the piece that the fluid flows into, then goes out to the caliper, its actuated via the rear brake lever.

read it to fast. not sure never taken one apart before. isn't there a snap ring you remove then pull it apart?

I already have all that apart, the snap ring is out, and the push rod is out, I just need to get the piston out.

soak it overnight in penetrating oil that usually helps with screwed up master cylinders.

Even if I do that. I still need a way to get the piston out, since you cant press down on it. How else would you get it out?

compressed air. blow it in the top hole above the piston. should push it out.
