The pads for the rear brakes are much larger than the stock pads and I need to get the piston to move back. I have tried a c clamp and it has move it but not enough. Is their any way get the piston to move.
Go to an autozone or other parts store. Rear brakes are screw in, and there is a tool that makes it way easy. Its about $10, or you can get a set of loaner brake tools at Autozone.
