Parking Brake
The parking brake operates on the rear wheels. The parking brake is applied against the brake pads. The brake caliper has an integrated parking brake mechanism. This is self-adjusting between shaft and piston each time after braking, see SPECIFIC FOOT BRAKE, REAR . When replacing the brake pads, a special tool is required so that the adjuster nut (3) can be turned back to the original position.

The tractive force on the brake cable produces a turning movement in the arm (15). The eccentric (14) transfers the force to the arm (13). The arm (13) converts the turning movement to a sliding movement on the adjuster screw (2). The adjuster nut (3) and the sealing cylinder (12) follow the movement towards the brake disc. The piston (1) presses the inner brake pad (19) against the brake disc at the same time as the brake caliper (17) and the outer brake pad (18) are pressed against the brake disc.
When the parking brake lever is released, the components return to the resting position.

21 Compensator
The upper control lever applies to model years up to and including 2007. The lower control lever applies to model year 2008 -.
Adjustment
Adjusting the mechanical cable for the parking brake is carried out at the lever. The adjuster nut (20) is located by the lever in the passenger compartment. The compensator (21) distributes the braking function between the rear wheel brakes.
