[s-cars] Rear Calipers

[Rbade12]

I always have a heck of a time screwing pistons in, even with the "proper" tool. Was the tool mated to the piston well enough that it was turning it as pressure was applied? I've found that a well placed c-clamp and a big 'ol channel locks carefully applied to the piston works well. I assume the caliper is off the car, therefore the e-brake isn't engaged. 
Your experience could differ, but, I once bought a set of rebuilt calipers and a couple years later they started acting wacky, so, I took them apart, there was barely any grease on both e-brake mechanisms. and one piston was pretty badly pitted. Since I've been a rebuilder, the hardest part of which are the circlips that are inside the caliper. [I alterd a lock ring tool to reach inside]. Try turning the piston again, unless it's really corroded it'll turn.

But, I’ve tried to wind back the calipers with a wind back tool and it bent 
the metal rod that’s supposed to twist the piston as it is compressed and 
wound back into the caliper body. So I must be doing something wrong? I’ve 
got like 4 of the rear calipers as parts to mess around with and they all 
seem to have the same problem, so it’s got to be me!
