The parking brake is a hand-operated system of drum brakes built into the rear brake discs. The inner center of the rear brake disc is shaped to form a brake drum.
Brake pads assembly
The brake shoes are mounted horizontally on an integrated brake dust shield and brake shield, forming a system with an upper secondary and lower primary brake shoe. The locking pins pass through holes in the dust shield and corresponding holes in the brackets of each brake shoe. Each pin is secured to the brake shoe by a spring clip. The pins allow movement of the brake shoe toward the drum surface during parking brake operation, but do not allow movement of the brake shoe sideways, away from the dust shield.
The expander and mechanical adjuster are located along the horizontal axis of the dust shield. The expander is located at the front of the dust shield, and the primary and secondary ends of the brake shoe brackets are located on it. The mechanical adjuster is installed at the rear of the dust shield, and the support point for the opposite ends of the brake shoe brackets is located on it.
The mechanical adjuster is used to adjust the clearance between the friction lining of the shoe and the drum during maintenance. The handwheel of the mechanical adjuster with a knurled head is accessible through a hole in the front of the brake disc. Adjustment is necessary when replacing the brake shoes or discs. To ensure satisfactory operation of the drum brakes, a bedding-in procedure is also required. For more information, refer to the chapter: Bedding-in the Parking Brake Shoes (206-05 Parking Brake and Parking Brake Actuator, General Procedures).
The contact of the corresponding ends of the upper and lower brake shoe brackets with the expander and mechanical adjuster is maintained by two return springs. The return springs are located between the ends of each upper and lower brake shoe and are secured in holes in the brake shoe brackets. When the parking brake is released, the return springs pull the brake shoes away from the drum.
Parking brake lever
The parking brake lever is located on the floor console, between the driver and passenger seats, and has a toothed sector and a locking mechanism controlled by a push button. One cable with a threaded stud connects the sector to the equalizer block and is secured with a lock nut or nut and washer.
The threaded stud allows the parking brake cable tension and parking brake lever travel to be adjusted during servicing. For more information, refer to: Adjusting the Parking Brake Cable (206-05 Parking Brake and Parking Brake Actuator, General Procedures).
The parking brake cable extends from the parking brake lever equalizer along the chassis to the rear parking brake extender. The parking brake cable protrudes from the front of the dust shield and is equipped with a tip that connects to the extender. Opposite ends of each left and right parking brake cable are equipped with a tip that connects to the equalizer block. The equalizer serves to ensure that the left and right parking brake mechanisms operate simultaneously when the parking brake is applied.
A microswitch is located on the base of the parking brake lever. When the parking brake is activated, the microswitch turns on the parking brake indicator lamp located in the instrument cluster. For more information, refer to the chapter: Instrument cluster (413-01 Instrument cluster, Description and operating principle).
