The OEMTOOLS Disc Brake Tool Kit assists in the replacement of brake pads on most 4 wheel disc brake cars making this disc brake caliper set an excellent addition to any disc brake caliper repair kit. Our disc brake caliper hardware kit can be used as a front or rear disc brake caliper tool set. This front and rear brake tool kit performs two important functions. The brake caliper retractor tool forces the disc brake caliper piston straight back into the caliper to provide clearance for new pads and the brake piston wind back tool also rotates the pistons back into the calipers on vehicles with self-adjusting parking brakes. Our brake caliper rewind tool includes 11 adapters for use on most domestic and imported cars that require clockwise rotations making this front and rear brake caliper piston tool set nearly a universal brake piston rewind tool. This front and rear brake caliper kit is for use on single piston calipers and the brake piston restorer set comes in a sturdy plastic storage case for easy organization and portability. The front and rear caliper piston tool kit is constructed from steel for strength and durability and the brake caliper compression tool set has a rust-resistant finish.
