Note. Plastic coated parking brake cables do not require periodic lubrication.
Specially coated parking brake cables are used to reduce the applied force and increase corrosion protection. The cables, covered with a plastic material, slide along the nylon inserts inside the guides.
Mechanical parking brake system
The parking brake lever is equipped with an indicator switch that closes when the parking brake is applied, illuminating the red warning light on the instrument panel.
The parking brake system is completely independent from the main hydraulic brake system. The parking brake is a mechanical system that locks the rear disc brakes through calipers. The system is activated when the parking brake lever is lifted, which activates the rear brakes via actuating cables. The mechanical lock of the lever keeps it in the selected position. When the parking brake is applied and the ignition is on, the corresponding indicator on the instrument panel lights up. The parking brake is released by pushing the button on the underside of the lever up a few millimeters and then lowering the lever to its lowest position. After the parking brake lever is fully released, the indicator on the instrument panel goes out.
Electronic parking system (ERV)
In the electronic parking system (ERV) the drive cables are tensioned by a motor in the electronic parking brake control unit.
Instead of the parking brake lever on vehicles equipped with an electronic parking system, there is a switch on the center console. Pulling the switch up activates the parking brake and illuminates the indicator lamp on the instrument panel. When the switch is pressed down, the parking brake is released and the indicator on the instrument panel goes out.
The motor in the electronic parking brake control unit pulls the right rear brake cable. The balancer, mounted on the drive cable, respectively pulls the drive cable of the left rear brake mechanism.
The electronic parking brake system allows you to implement the following functions:
- Static activation/deactivation.
- Dynamic activation/deactivation.
- Automatic release.
