Parking Brake System: Description and Operation

Parking Brake Assembly General
the parking brake operates through the rear caliper piston acting directly on to the disc using the pads. the parking brake is self-adjusting, with the adjustment being made on the piston itself. A tool is required to wind back the adjuster when fitting new pads. the parking brake is operated from the handbrake by two Bowden cables with a compensator fitted inside the cabin area and an adjustment nut under the handbrake lever in the center console.



Parking Brake Assembly Adjustment Notes

The parking brake operates through the rear caliper piston acting directly on to the disc using the pads. The parking brake is self-adjusting, with the adjustment being made on the piston itself. A tool is required to wind back the adjuster when fitting new pads. The parking brake is operated from the handbrake by two Bowden cables with a compensator fitted inside the cabin area and an adjustment nut under the handbrake lever in the center console.

Parking Brake Adjustment
The procedure to set up the handbrake correctly is as follows:

- Slacken the parking brake cable-adjusting nut at the handbrake lever. Wind back the rear brake caliper piston using the special tool. Fit brake pad linings into the caliper. Ensure the pad retention spring is fitted in the piston groove. Fit the caliper over the brake disc and secure it to the bracket.
- With the parking brake lever released, check whether the stop of the control lever makes contact with the grooved pin and the circular section at the end of the cable is correctly located in the caliper support. (Cable support has a torsion lock. With the correct fit, cable twisting is impossible.)

- Adjust the parking brake cable on the adjusting nut at the parking brake lever until the control lever on the calipers lift 1-2 mm from the grooved pin. The measurement between the grooved pin and control lever is carried out using a feeler gauge.
- Slowly and forcefully press the brake pedal several times (One shot adjustment). Forcefully pull parking brake and then release. Check wheels for freedom of movement.

Note: Adjustment of the parking brake cable is only carried out:

- A. When the parking brake cable is replaced.
- B. When the brake caliper is replaced.

If linings or discs are changed, all that is necessary is to move back the piston.
