The Snap-on Two Pin Brake Piston Tool, No. BTPUCK2, is a universal and adjustable twin pin brake caliper piston resetting puck that eliminates the need for an assortment of different sized pucks to service wind-back piston style vehicle brake calipers. The fully adjustable rotating body dials in the twin pins, center-to-center distance, enabling insertion into a range of brake caliper piston face slots. An exclusive rotating lock secures twin pin spread/stroke for perfect fit, and the slim profile eases servicing of narrow or “micro-type” calipers. The BTPUCK2 is equipped to work with a 3/8” ratchet or wind-back tool on wind-back brake caliper pistons with two or four faced slots.
