摘要： The invention relates to a hydraulic parking brake equipped with a parking brake device, in particular for motor vehicles and comprising a brake housing, in which a hydraulic service pressure chamber is delimited by a brake piston. According to the invention, the parking brake device acts on the brake piston and can be locked by means of a locking device once the brake is applied and comprises an energy accumulator that has at least one integrated spring element and co-operates with the brake piston. The aim of the invention is to provide a simple, cost-effective parking brake function that complies with legal requirements. To achieve this, the parking brake device can be actuated by a pressure that is regulated in the service pressure chamber (7) and that can be used to charge the energy accumulator (10).
