The caliper is a single piston design that is mounted to a anchor bracket with two pin bolts. The anchor bracket mounts to the steering knuckle with two bolts. Hydraulic pressure, created when the brake pedal is depressed, acts equally against the piston and the bottom of the caliper bore to move the piston outward and to slide the caliper inward. This action forces both pads against the rotor, creating friction to stop the vehicle.

When the brake pedal is released, line pressure is released and the seal and seal groove cause the piston to retract slightly, resulting in less pad wear and pad drag on the rotor. Pad wear is automatically compensated for by the sliding action of the caliper.
