Abstract: An electromechanically actuable parking brake for motor vehicles is disclosed. The brake includes at least one electromechanical actuator whose rotational movement is converted into a translational movement by an actuating unit, and which moves at least one brake element in such a way that at least one brake lining which is connected to the brake element is pressed with a locking force against a rotor which is connected to a motor vehicle wheel, wherein the current consumption of electromechanical actuator when the parking brake is engaged and/or released can be acquired. Furthermore, a method for operating the electromechanically actuable parking brake is also disclosed.

Abstract: The invention relates to a method for operating a hydraulic braking system for motor vehicles, comprising a service brake system and a parking brake device, with the service :Drake system including a pedal-operable hydraulic pressure generator, to which two brake circuits with at least one externally controllable hydraulic pressure source are connected, and a hydraulically operable front-axle wheel brake provided with inlet and outlet valves and a hydraulically operable rear-axle wheel brake provided with inlet and outlet valves are associated with each one brake circuit, and with the parking brake device including means for arresting the brake pistons of the rear-axle wheel brakes, the brake pistons being acted upon by hydraulic pressure supplied by the pressure source for the purpose of activation or deactivation of the parking brake device.

Abstract: Disclosed is an electromechanically actuated parking brake for motor vehicles that is designed as a drum brake of the ‘Duo-Servo’ type, including a floatingly supported expanding lock which is operable by an electromechanical actuator arranged on a wheel carrier, and which is essentially composed of a threaded-nut/spindle assembly, the threaded nut of which is driven by the electromechanical actuator, and of two thrust members. At least one spring element is provided in the flux of force between the threaded-nut/spindle assembly and at least one of the thrust members. This provision allows compensating losses of application force, while the set application force is maintained in a reliable manner.
