OP Parts caliper

I was doing a rebuild on my 86 Carrera brakes and the fronts worked out fine but my rears appear to have a frozen piston on each caliper. With some soaking and a brake shops air pressure we were able to free up one of the calipers but the passenger rear has one stuck piston. I am going to soak it in brake fluid and try again but the mechanic did not think it would work. In my search I have found a source that has a good price (under $100sale list was $400) for each caliper. They are manufactured by OP Parts. The ATE's or remanufactured from PMB are 300/pair. Does anyone have experience with this brand for use as a caliper?

If you do a little searching, you can find the new ATEs for $235.

For Porsche brakes it is a no-brainer for me, PMB Performance in Sandy, Utah. Eric Shea is the brake guru and I will not trust my brakes to anyone else.

I had this problem with a caliper once. With the caliper off the car I put it in a vice with some packing to get the vice to act on the piston and forced the piston back in. There was an almighty bang and I thought I had broken the caliper in half as I was using a lot of force, but, no, it had pushed the piston back in. Then I cleaned up the bore, refitted it to the car and pumped the piston out with the brake pedal. I was then able to rebuild the caliper. Worth a try.

+1 on hooking it back up and pumping it out using the brake pedal. It always works for me.
