For 1990-2009 cars only

The caliper has a single bore and is mounted with 2 mounting bolts. Hydraulic pressure, created by applying the brake pedal, is converted by the caliper to a stopping force. This force acts equally against the piston and the bottom of the caliper bore to move the piston outward and to slide the caliper inward, resulting in a clamping action on the rotor. This clamping action forces the linings against the rotor, creating friction to stop the vehicle.

    • Replace all components included in the repair kits used to service the caliper.
    • Lubricate the rubber parts with clean brake fluid to ease assembly.
    • Do not use lubricated shop air on brake parts, as damage to the rubber components may result.
    • If any hydraulic component is removed or disconnected, it may be necessary to bleed all or part of the brake system. Refer to Hydraulic Brake System Bleeding.
    • Replace the brake pads in axle sets only.
    • The torque values specified are for dry, unlubricated fasteners.
    • Perform the service operations on a clean bench, free from oily material.
