Duo Servo Drum Brakes

To meet increasing requirements in regard of safety, comfort and networking the electric parking brake is progressively replacing the mechanical hand brakes. In addition to the improved safety and comfort for the customers it offers the car manufacturers more freedom and options for the vehicle interior design.  The Electric Parking Brake in general replaces the mechanical activation via the hand brake lever by an electrical switch and electromechanical actuators building up the required clamp forces.  The EPB-DS ("duo-servo") is a solution for duo-servo brakes. The EBP-DS is used especially in premium-class vehicles, light commercial vehicles, sport cars and SUVs in whose case separating the service brake and the parking brake is particulary important.  The system consists of two electrical actuators which are integrated in the Duo-Servo brakes, and an electronic system that is integrated into the ESC and has the EPB-specific operation software, acc. to VDA recommendation 305-100.  The EPB-DS (EPB applied to Duo-Servo drum brakes) consists of an electrical actuator which are integrated in the Duo-Servo brakes, and an electronic system that is integrated into the ESC. It offers the possibility of using an electro-actuated parking brake in premium-class vehicles, light commercial vehicles, motorhomes, sport cars and SUVs in which case separating the service brake and the parking brake is particularly important.
