What is electronic brake caliper?
Electric Park Brake (EPB) is a caliper with an additional motor (motor on caliper) that operates the parking brake. The EPB system is electronically controlled and consists of the EPB switch, the EPB caliper and the electronic control unit (ECU).
Hot brakes lead to a loss in clamping force in mechanical parking brakes. But with EPB, roll-off protection monitors and controls the clamping force in order to ensure a safe parking brake condition irrespective of temperature and friction loss. This prevents the vehicle from rolling off even under extreme temperatures. This provides important added safety especially in mountainous regions.
