An electropneumatic parking brake system for a utility vehicle includes a pilot module configured to control at least a first control pressure. The pilot module has a pilot store connection configured to receive a store pressure from a compressed air device and at least one pilot valve combination. The electropneumatic parking brake system further includes at least one manually actuatable piston valve connected to a valve store connection and having a parking brake connection. The parking brake connection is ventilated in a first switching position of the piston valve and a parking brake pressure at the parking brake connection is controllable in a second switching position of the piston valve. The piston valve has a first pneumatic control connection at which the first control pressure is configured to be controlled in order to pneumatically switch the piston valve.
