Parking Brake Adjustment Drum Brake

Note: This vehicle utilizes a self-tensioning, or self-adjusting park brake cable system. The park brake system does not require adjustment under normal operating conditions. The tension on the park brake cables can be disabled and enabled when necessary during service of the drum brakes and/or the park brake system.
