GM Service Manual Online
For 1990-2009 cars only

The system is a self adjusting component and is located on the left side of the kick panel. This system will not require periodic adjustment. However, there is an adjustment feature built in the system located along the front left of the frame called the equalizer.

The park brake is not designed for use in the place of service brakes. Apply only after the vehicle is brought to a complete stop, except in an emergency. Before working on the park brake system, make sure the service brakes are in good working order and adjusted properly.

Park Brake Lever

The lever is activated by foot pressure. The lever has a clutch mechanism to allow varying degrees of park brake application. The release handle on the instrument panel allows the driver to release the park brake.

Park Brake Cable System

Notice: Handling of the parking brake cables during service requires extra care. Damage to the nylon coating reduces the corrosion protection. If the damaged area passes through the seal, increased parking brake effort could result. Avoid contacting the coating with sharp-edged tools, or the sharp surfaces of the vehicle underbody.

The brake uses a cable system that includes one front cable and two rear cables. The front cable connects to the lever on one end and the connector on the other end. The rear cables attach to the equalizer and connector on one end and the park brake struts in the drum brakes on the other end.

This vehicle is equipped with coated cables. The wire strands are coated with a nylon material that slides over plastic seals inside the conduit end fittings. This is for corrosion protection and reduced effort.

Brake Lamp

The BRAKE warning lamp in the instrument cluster turns on when the park brake is applied. The lamp can also be turned on by the switch in the combination valve and the antilock brake system.

Park Brake Indicator Switch

The indicator switch located on the park brake lever, serves as the device to turn on the BRAKE lamp in the instrument panel when the park brake is applied. The switch also turns off the BRAKE lamp in the instrument panel when the park brake is released.

Daytime Running Lights

Vehicles equipped with a Daytime Running Light system (DRL), use the park brake switch to turn the headlamps off when the ignition switch is in the ON position and the park brake is applied.
