I didn't have an air compressor to use, but actually just a good bike
pump with the hose held tightly against the pipe hole popped mine right
out. Since I was doing a complete rebuild, I went ahead and used some PB
Blaster to get it loose first. Then once it was out, I used some brake
cleaner which dries nicely without residue and finally relubricated the
new piston with brake fluid.

Subject: Re: stuck piston/caliper
Todd, have you tried compressed air? Probably a little less messy. Put
the loose piston back in and find a way to clamp it so that it wont come
out while you apply air to try and free the stuck piston. I think I
clamped an old brake pad to the loose piston with a couple of c clamps.
When it finally
comes out, you should be able to get out the one thats loose. Be sure
and do
this with safety glasses, away from any cars, and keep your fingers out
from between the pistons. The air will blow out any remaining brake
fluid with quite a force.

having a little trouble getting one of the pistons out of the caliper on
my tr6. i tried using the hydraulics to get them out. one came out
enough to gently tap it out with a punch. my guess is to clean it up &
put it back in & hold it with a clamp & try again for the other?
