Please help: trying to replace rear pads and rotors, any trick to expanding the caliper piston???
<center><img src="http://www.tirerack.com/brakes/images/brembo/replacement_rotor_with_box.jpg"></center><p>I tried using to wooden wedges which worked great for the front rotors, but the rear caliper piston won't budge...car is sort of immobile until I can figure this out, any suggestions would really be appreciated!
Thanks,

The piston needs to be pushed in and turned to get it to retract
I did mine 2 weeks ago and used a pair of pliers in the 2 little grooves to push in and turn the piston. Its not easy and requires quite a bit of force.

this is acually not my audi, but I wonder if the push and turn thing is universal...although the...
front rotors did not need to be turned...It's a 1989 Ford Tuarus SHO. I figured no one would have specific knowledge, but I thought I might be able to get some general info...
Thanks for the help, I will see if it will turn, BTW, which way did you turn it? clockwise, counter clockwise?
Thanks again,

open the brake res. in the engine bay to relieve pressure and get a very big C clamp to
turn down the piston!!
i did this two weeks ago and bought every little tool possible from the Infamous "cube" to the brake spreader nothing worked!!!!!!!!!
and dont worry as long as you dont disconnect and barke lines you dont need to bleed you brakes!!
GOOD LUCK

The reason you have to turn the rears is because of how the E-Brake works
there's a mechanism which is meant to keep the throw of the ebrake lever constant despite the fact your pads are wearing. This takes up the slack and gives you a consistent feel at the ebrake handle. This is what you're effectively resetting when you're turning the piston. The fronts don't have anything like that...hence the lack of need to turn them.
