I need to replace both rear calipers on my 91, I have a good pair but I'm having issues turning the pistons back into the housing for the new pads. I do have the proper tool set. Ive done it on my Mini coopers and my 93L while the calipers were on the car. These are on my bench so do the E-Brake pulleys need to be in a certain position to be able to turn the pistons ? If I manually actuate the E-brake brackets the pistons do move out a bit so I dont think they are frozen.

I use a large C-clamp and curved jaw vise grips to compress and turn piston. I also lift rubber boot on end of piston and spray lube boot and groove it rides in so when piston turned clockwise to retract it boot won't stick to piston.

If parking levers are free to move just leave then alone as your compress and rotate piston.
