Each drum brake mechanism contains a pair of brake shoes mounted on a backing plate, which is attached to the rear hub carrier. The brake shoes are located inside the drum, which is integrated into the rear brake disc. The orientation of the brake shoes LH (left) and RH (right) brake mechanisms differs by 180°.
When the parking brake control unit tightens the cables, this force is transmitted to the actuator lever on one of the brake shoes. The actuator lever rotates relative to a cross-shaped strut, which moves the brake shoes apart and brings them into contact with the rear brake disc drum. The gap between the brake shoe and the drum is set using two mechanical adjusters, accessible through a hole in the brake disc. One of the adjusters has a conventional toothed design. The second adjuster is a wedge adjuster, controlled by a hexagonal-head screw.
After replacing brake pads or brake discs, a bedding-in procedure must be performed to ensure normal operation of drum brakes. For more information, refer to Parking Brake Shoe and Lining Adjustment (206-05 Parking Brake and Actuation).
Before removing the brake disc from the vehicle, the power supply to the parking brake control unit must be disconnected. Operating the parking brake switch with the brake disc removed may cause the parking brake control unit actuator to jam.
