Full Version: compressing rear brake caliper pistons
You're currently viewing a stripped down version of our content. View the full version with proper formatting.
Im doing a rear brake job on the TC and have already had to replace the drivers side rear caliper due to the piston not compressing back in. Now Ive gotten to the passengers side and the piston wont move either. Is there some kind of trick with ABS equipped cars(my first brake job on an ABS car) or is this piston just stuck too? Please advise asap.
You use a pair of needle nose pliers in the grooves on the pistons to "screw" them back in while applying pressure. Just watch your fingers if the pliers slip! It helps to take the bleeder loose and just bleed them afterwards. There is a special tool that makes this job simple but its rather expensive for a set of them.
they screw in
Like has already been stated, push and screw and they'll retract. Don't know about the "expensive" tool, but the cheap one I bought didn't fit the grooves without modification.

Good luck!
You can get the special set to screw the calipers in at Auto Zone. They are about $35.00 but well worth it. I think they rent them also.

Ugh! It wont budge with the needle nose pliers. I tried it in both directions with the bleeder valve cracked.
It will screw in with the pliers, but it is EXTREMELY hard to do this way. You have to press so hard while turning that it's a wonder that everyone that has tried this doesn't have a hole through the center of their hand. The tool that you should be using, as some have stated, I believe can be "borrowed" from Autozone. Picture a steering wheel puller that fits between the outer 'arms' of the caliper and the piston, and it pushes instead of pulls. As you twist the "pusher" tighter, the twisting action also screws the piston in. It's so easy that it will make you sick that you ever tried to touch the thing with pliers. Now, go bandage up your hands and give autozone a call. Good luck to ya.
