The Cal-Van Tools 2- and 3-Pin Adjustable Brake Piston Tool, No. 723, designed to rotate brake pistons back into the caliper on most domestic and import vehicles with self-adjusting parking brakes, gives the technician the ability to rewind brake pistons using a 1/4" extension. This single tool replaces kits that contain up to 20 parts by having universally adjustable 2- and 3-pin configurations. The tool fits on a standard 1/4” ratchet or breaker bar and works on both right- and left-hand pistons.
