I use air pressure to pop the pistons out, it doesn't take much! Try to remove one at a time, put a block of wood between two of them, and use a small C-clamp to hold the third. The apply a bit of air pressure to pop the 4th out. Replace seal (make sure you put brake fluid on it first) and reinsert rebuilt piston. Then move on to the other 3.

 

I got the caliper from the place in CO, impressed that they can do overnight shipping. The prices is like dealer prices minus 3%. I guess it is the price for overnight shipping. I just hope my right rear isn't frozen!

 

The install was relatively simple, the bracket and bleeding brakes suck. Anyway as I had expected, the right front was also stuck but the right rear was okay. Lucky I got the other caliper.

 

What place in CO? Curious.

I have always gotten seals for rebuilding from RacingBrake.

 

Rmeuropean

i will take the seals apart to see if the piston is good or bad. I wonder if they both fail due to heat or both jusy died around the same time. It was on rs14

 

RMeuropean has some good prices and are quick to ship. FCPeuro is more expensive, but you can send wear items back for their lifetime warranty; I'm about to send back a set of rotors and some wheel bearings.
