    BRAKE SERVICE PROCEDURES FOR Pontiac G8 AUTOMOBILES

    Includes anti-lock brakes, disc, drum, power and hydraulic brake services diagnostics and procedures for domestic and imported Pontiac G8 cars and light trucks from 1990+.

    Disc Brakes -> AC-Delco Single Piston Rear Disc Brake -> Description
    Vehicle: 2009 Pontiac G8 GXP 6.2 V8 GAS

    On all models except Grand Prix, the caliper assembly has a single bore and is mounted to the support bracket with two mounting bolt and sleeve assemblies, Fig. . 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 piston bore to move the piston outward and to slide the caliper inward resulting in a clamping action. This clamping action presses the linings against the rotor, creating friction to stop the vehicle.

    On Grand Prix models, the caliper has a single piston, a...
