GM Service Manual Online
For 1990-2009 cars only

This braking system uses a BRAKE warning light located in the instrument panel cluster. When the ignition switch is in the START position, the BRAKE warning light should glow and go OFF when the ignition switch returns to the RUN position. Whenever the parking brake is applied and the ignition switch is ON, the BRAKE warning light should glow.

When the brake is firmly applied, the parking brake should hold the vehicle with ample pedal travel remaining. Inspect for frayed cables, rust, etc. or any condition that many inhibit present, or future, free movement of the parking brake lever assembly.
