A parking brake module for a pressure medium-operated brake system of a vehicle having a parking brake function enabled by at least one spring brake cylinder includes a first valve device that increases the amount of pressure medium and has an inlet that can be connected to a pressure medium reservoir, an outlet that can be connected to at least one spring-loaded part of a spring brake cylinder, and a control input connected to a control line. A second valve device encompasses at least one first connection used as a trailer control valve connection and can be connected to a trailer control valve to control a trailer brake. To provide a valve concept for different vehicle configurations, particularly including an anti jackknifing function, pressure prevailing at the first connection can be adjusted regardless of pressure prevailing in the pressure medium reservoir and at the outlet of the first valve device.
