Can anyone tell me if the piston in the rear caliper on a 04 auto coupe is a twist in piston?
I have one that I believe is froze up.
And I think they are just push in pistons, but not sure.

Not sure about the coupe, bu the rears on my 04 sedan are standard type, not scre in. If they are screw in there should be soem type of ribs, or cut out to turn them.
