How Do You Use A Disc Brake Piston Tool?
Brake calipers all work under the same premise. A hydraulic piston extends from the caliper bore when demand is placed on the brakes. The movement of the piston squeezes the friction material of the brake pads against the metal surface of the rotor. When replacing brakes, the pistons must be retracted to make room for the thicker pads and/or rotors. Not all caliper pistons employ the same procedure to retract the pistons, however. Rear calipers can sometimes require the piston to be turned clockwise (or counterclockwise in some cases) to retract the piston. Knowing which type of caliper you intend to use the disc brake piston tool on will help prevent damage to the caliper or tool. Support the removed caliper to the suspension or frame of the vehicle with a bungee cord so it does not hang from the rubber brake hose. This will prevent damage to the brake hose. If applicable, remove the pads from the caliper. Some vehicles use pads that remain in the caliper mount and removing them from
