Parking Brake: Overview
WARNING: This page is about a different car, the 2018 Land Rover Discovery Sport, 2017 Land Rover Discovery Sport, 2016 Land Rover Discovery Sport, and 2015 Land Rover Discovery Sport. However, it is still accessible from the selected car via links, so may be relevant.
The Electric Park Brake (EPB) is an electrically actuated system that operates the calipers on the rear brakes. The system consists of:
- An EPB switch
- Two EPB actuators
- Clutch pedal position sensor (manual transmission vehicles only)
- Two warning indicators
- Anti-lock Brake System (ABS) control module
The EPB is controlled by the ABS control module, which uses the EPB actuators to apply and release the rear disc brakes. Operation of the EPB is initiated by the EPB switch and software within the ABS control module. The EPB has the following operating modes:
- Static apply/release
- Ignition off apply (manual transmission vehicles only)
- Drive away release
- Automatic transmission apply/release
- High temperature re-clamp
- Driver exit warning
- Dynamic apply
- Roll away re-clamp
Signals from other vehicle systems for operation of the EPB are transmitted to the ABS control module on the High Speed (HS) Controller Area Network (CAN) chassis systems bus and the HS CAN powertrain systems bus.
