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 III position, the BRAKE warning light should glow and go OFF when the parking brake lever is released. Whenever the parking brake is applied and the ignition switch is II, the BRAKE warning light should glow.

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