For 1990-2009 cars

The caliper has a single bore and attaches to the steering knuckle with two mounting 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 linings 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 be slightly retracted, resulting in less shoe and lining drag on the rotor. Lining wear is automatically compensated for by the sliding action of the caliper.

For a specification description of the rotor utilized for the front disc brakes, refer to Component Specifications .
