85 gsl. How do I compress the rear brake pistons?
As noted. I am in the middle of a rear brake pad job and cannot compress the piston. Is there a special tool I need to push and turn the piston to make room for the new pads? It will not just push straight in. There is two divots on the piston which suggests a special tool for this job.
Any help would be appreciated.

Yeah, shutup kid.
There is a special tool for it, but you can also use pliers. Just put the jaws of the pliers in the divots, and twist. If the piston doesn't want to turn, then put a screwdriver between the handles of the pliers and use that for leverage.
I had the special tool, but none of the sides really fit right, so I ended up using the pliers anyway

I know that works for front pistons, but I tried to just compress the rear pistons with no luck. I am pretty sure they are not seized.
I did a rear pad job on a 90 something olds with rear disc and we had to compress the piston with a C clamp while turning the piston clockwise.

dosen't work that way. you need that special tool. you can rent it at an auto store. I got rented mine from Auto Zone over here in Los Angeles, don't know whats over there. That tool would be the easiest way for you to "twist" back the piston.

Oh yeah, remember to bleed the brakes properly. And have plenty of brake fluid handy.
