Electronic parking brake

An electronic parking brake (EPB), also known as an electric parking brake or electric park brake, is an electronically controlled parking brake, whereby the driver activates the holding mechanism with a button and the brake pads are electrically applied to the rear wheels. This is accomplished by an electronic control unit (ECU) and an actuator mechanism. There are two mechanisms that are currently in production, Cable puller systems and Caliper integrated systems. EPB systems can be considered a subset of Brake-by-wire technology.

First installed in the 2001 BMW 7 Series (E65), electronic parking brakes have since appeared in a number of vehicles.
