The parking brake actuator is mounted on the rear cross beam, underneath the vehicle. Operation of the actuator is controlled by the control module in response to parking brake switch requests from the driver.

A hall sensor is located within the actuator and provides positional information back to the control module. The principle function of the hall sensor is to ensure the actuator fully releases the parking brake when a static release request is made. The signal provided by the hall sensor is compared to configuration information contained within the control module software to determine when a full release has been carried out.

Further information on the hall sensor can be found in the 'Principles of Operation'  section below.
