The EPB is the acronym for Electric Parking Brake system. The conventional parking brake systems are muscular-energy brake systems and are operated by purely mechanical means via lockable hand levers or foot pedals or via a crankgear. In Electric Parking Brake(EPB) systems, the control(operating) force is generated by an electric drive. Operation and control are effected electrically by means of a switch. The EPB can only be operated when the vehicle is stationary. The systems communicate with each other through a CAN data link.
