  "textContent": "The invention relates to a parking brake module of a parking brake device, having an electronic control device (20), at least one solenoid valve (14) actuable by the control device (20) and a pressure medium quantity amplifying valve (16) for applying pressure medium to at least one brake actuator (40). Furthermore, the parking brake module (2) has an emergency release pressure medium connection (44) and a double check valve (46), by means of which an emergency release function of the parking brake device can be provided. For this purpose, the emergency release pressure medium connection (44) is connected via a first pressure medium line (48) through a check valve (52) to the supply inlet of the pressure medium quantity amplifying valve (16) and via a second pressure medium line (50) to an inlet of the double check valve (46). Furthermore, the invention relates to a brake system with a parking brake device having an emergency release function of the parking brake, a vehicle therewith, and a method for operating such a parking brake device with emergency release function.",
