I'm trying to change the brake pads on the rear of my '96 STS and I can not get the piston pushed into the caliper, actually I can't get it to move at all. I've disconnected the brake line and removed the bleeder valve but nothing. The trouble is I can't get the old pads back on to take it to a mechanic. Any suggestion would be greatly appreciated.
on many cars the caliper pistons have to be screwed back maybe this is the case with your car...youll need a special tool to do this which youll get from your local autostore, failing this your piston could be seized...leave it to soak in WD40..and try later
As stated, rear calipers, need to be screwed back in. Do not use a c-clamp to try and press the piston in, as you would a front caliper. Yoy will damage the caliper. I did not buy the special tool when i did my brakes. A pair of needle nose pliers worked like a charm. Just put the plier tips into the recesses, and turn clockwise, as you are viewing the piston. It takes a little effort to get it to begin turning, but after it starts, it turns very easily. Hopefully you haven't damaged the caliper. Good luck.
Thanks for the input guys. I talked to a friend and he told me they needed to be threaded in and not pressed. I ended up buying a tool for future use and to make sure I don't damage the caliper.
Thanks again for the help.
