Product Description

What is Electronic parking brake？

An electronic parking brake (EPB), also known as an electric park brake in North America, 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.

Functionality

Apart from performing the basic vehicle holding function required of park brakes, the EPB systems provide other functions like automatic release of the park brakes when the driver presses the accelerator or slips the clutch, and re-clamping using additional force on detection of vehicle motion. Further, the hill-hold function, which applies brakes to prevent roll-back when pulling away on a gradient, can also be implemented using the EPB.
