How do I get the cylinder on the caliper to go in so I can install new pads. This is on the rear
brake job on 2003 Buick Park Avenue
Use a large C clamp to compress the caliper piston. Be careful if the car has an integral park brake that you dont push the caliper in too far or you may damage the park brake mechanism. Push it in just enough to remove and then install the new thicker pads.
