hi i am hving trouble doing my rear brakes on my 94 regal. can anyone help me out here. what do i have to do to get my piston in my caliper to go back. i tried pushing it back with c clamps and it would move back. Can anyone help me please.:banghead:

There is a specific tool for this job, the piston must be turned clockwise as it being pushed in, no other way. Either buy one ( comes in a set) or try to rent one.

what would tool be call and is it expensive.

You should be able to get one of these at your local auto parts store.
