Inner Front Caliper Piston is way out

[logdrum]

Hi all,

I may not have searched properly but I cannot find info on how to compress the inner piston of the front right caliper on my 1983 W123. The pads were worn unevenly and the inner pad was almost bare metal. The left brakes were a breeze to replace but the right wheel was different. The piston needs to move ~2mm for me to be able to slide new brake pad in. I used the old pad and used one of those adjustable pliers to push the pistons in. Is the caliper shot. I open my brake fluid reservoir cap as well. But it is really hard and won't budge

C-Clamp needed right? Any way to diagnose if the the caliper piston is shot.

BTW I replace the left brake without removing the caliper. The wheel in question the rotors are the same thickness as the left and not scored on the inner side.


Thanks
