Rear brake piston won't compress. Bad caliper?
 

Tried changing my rear brakes last night. The drivers side is worn down to the metal. The pass side still has about 50% meat left. Its the pass side caliper that I can't compress the piston enough to get the new brakes on. Or even get the old brakes bake on. I am guessing I need a new caliper?
I also tried to bleed them a little to see if it would help. Nadda.
Turned a 6" C clamp into a pretzel in the process :mad:

you have to turn the piston on the rear caliper because of the internal parking brake mechanism. push in and turn clockwise.

make sure you line up the little divots in the piston to the tits on the pad when you're done.

.... :rolleyes:
Thanks man. Cheaper then a new caliper! :D I'll try it when I get home from work!

+1....

LOL HEHEHE

do not use C clamps in the rear, you will damage the pistons.

Use WD40 or other penetrating lubricant and sprayaround the piston and unde the seal.

I didn't know I was supposed to 'screw' the piston in. I will try it when I get home tonite

When I did mine i took it to a local shop(just the caliper) and they compressed for me for $5 with like a special key. It took them 5 minutes to do it.

You cant rent the rear caliper tool kit from AutoZone. Makes the job infinitely easier, and then just return when you're done and get your money back.

isnt it called a pry bar lol...

Naaa

YUP thats the one the guy use when he winded mine back.

Just an update.

Went to advance auto parts this morning and picked up the tool I needed for $10. Its square and seems universal. It did the trick. Thanks for pointing me in the right direction!!! :)

^ That's the one I have. The "cube". Heheh..

Thanks this thread really helped me. I tried the C clamp method last night and it didn't work. I called the dealer and they wanted $355 for a new rear caliper.. I'll try turning it back tonight.

Most car part places have remanufactured (perfectly fine) rear calipers for about $100 each.

^^ yup, got my rear calipers for i think like 82 bucks each with core

Well I got the tool fro Auto Zone. Turned the caliper pistons back and got the car back on the road. The brake pedal is squishy though so I need to bleed the brake lines. Thats ok the brake fluid is old and it needs to be flushed anyway. That is a job I will pay someone to do.

I also got mine from Auto Zone. Works good.
