This easy-to-use tool pushes the pistons back into your brake calipers for quick and easy brake pad changes. Using the wrong tool can damage pads, pistons, and seals. This pistol-grip tool pushes squarely against the piston to prevent cocking the piston in the bore. Works on virtually any caliper* -- floating or fixed, single, twin, or 4-piston. You can even use it on huge 6-piston monobloc calipers. The jaws can even be rotated 180° so you don't have to pull the caliper off the car. Steel jaws measure 3 1/2" W x 1 1/2" D.
* Note: Not for parking brake calipers which require the piston to be rotated in order to retract.
