An electropneumatic parking brake device is for supplying air to and exhausting air from spring-loaded accumulator brake cylinders of an electronically controllable pneumatic braking system for a vehicle and includes a parking brake valve unit with a reservoir port for receiving reservoir pressure from a parking brake reservoir. The parking brake valve unit sets a parking brake pressure at a spring-loaded accumulator port depending on a parking brake signal. A non-return valve is arranged between the parking brake valve unit and the parking brake reservoir to prevent compressed air from flowing back from the parking brake valve unit to the reservoir. A bypass valve is provided which can be switched to supply air to and exhaust it from the spring-loaded accumulator port. The bypass valve is activated and switched independently of the parking brake valve unit.
