摘要

The brake device (1) has a valve unit (26) connected with a parking brake control device (30). The parking brake control device is switched into a driving position by an actuating element, when the pressure at a pressure input terminal (44) is smaller than the predetermined limit pressure. The parking brake control device is switched into a parking brake position by the actuating element, when the pressure at the pressure input terminal is larger than or equal-to predetermined limit pressure.
