Park Brake System Description and Operation
| Park Brake System Description and Operation |
| Note | ||
|
Plastic coated park brake cables do not need periodic lubrication. |
Coated park brake cables are used to reduce apply effort and increase corrosion protection. The cables are coated with a plastic material which slides against nylon seals inside the conduit end fittings.
| Electronic Park Brake System |
In the electronic park brake (EPB) system the brake cables are pulled by the motor in the electric park brake control module (EPBCM). Refer to Electronic Parking Brake Control Module Description .
There is a switch on the centre console instead of a handbrake lever. With the switch pulled up, the handbrake is applied and the hand brake warning indicator goes on in the IPC. By pushing it downwards the park brake is released and the warning lamp goes out.
The motor in the EPCM pulls the cable to the right-hand rear wheel caliper. An equalizer is mounted on the cable and pulls the cable to the left-hand rear wheel.
The function is divided into:
| • |
Static apply/release
|
|
| • |
Dynamic apply/release
|
|
| • |
Automatic release
