GENERAL DESCRIPTION AND SYSTEM OPERATION
PARKING BRAKE
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 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. Check for frayed cables, rust, etc. or any condition that many inhibit present (or future) free movement of the parking brake lever assembly.
