  "textContent": "A brake system for a utility vehicle includes: an electronic brake controller unit, a pneumatic parking brake circuit with at least one spring energy cylinder, a parking brake valve to control a parking brake pressure in the parking brake circuit, and at least one 3/3-way valve arranged in a pneumatic line of the parking brake circuit between the parking brake valve and at least one of the spring energy cylinders. The 3/3-way valve is actuable by the electronic brake control unit, and is configured to ventilate the pneumatic line between the 3/3-way valve and at least one of the spring energy cylinders to a predefined pressure, so as to cause the at least one of the spring energy cylinders to allow a brake, which is assigned to the spring energy cylinder, to pass into engagement.",
