A method and a device for tightening a hydraulic parking brake are disclosed. In the method, a tightening force is generated in a first step by creating a hydraulic pressure in a parking brake circuit. To this end, a pressure generating unit driven by an electric motor is used. In a subsequent step, at least one motor-related parameter which permits a conclusion about the hydraulic pressure prevailing in the parking brake circuit is detected. Subsequently, an activation of a tightening force assistance device takes place depending on the detected motor-related parameter and without the necessity of providing a pressure sensor.
