Brake Caliper Rebuild - Dual Piston - Seals, Dust Boots & Dust Boot Clip

This video will show you how to rebuild a brake caliper assembly. The rebuild video was performed on a 1992 Mitsubishi 3000 GT. If you found yourself in a situation replacing brake pads and the caliper pistons won't retract into the caliper; or you got the caliper pistons pressed in but the wheels lock up the first time you pressed down on the brake pedal, the caliper assembly should be rebuilt. Moisture build up in your brake fluid or a split caliper piston boot can result in corrosion or rust build up on the caliper piston slide surfaces. The outer portion of the piston rides on a internal rubber seal recessed in a groove inside the caliper piston hole. It's a very tight fit (to prevent brake fluid from leaking) and any corrosion on the piston slide surface will prevent the smooth movement of the piston(s). Caliper rebuild kits are inexpensive and no expensive specialty tools are required to rebuild caliper assemblies. They consist of piston seals, boots and a boot retention ring/clip.
