Abstract
A known brake circuit comprises a mechanical brake-pressure control device and an electrical brake-pressure control device. The mechanical brake-pressure control device is furnished for assuring an emergency operation in case of a fault of the normally predominance-taking electrical brake-pressure control device. The known brake circuit can be controlled only then in a load-dependent way, when both the mechanical as well as the electrical brake-pressure control unit comprise a load-dependent automatic brake-pressure controller. According to the invention, a restraining device (103 3, 5) is furnished in the mechanical brake-prerssure control device (103 3, 5). The restraining device (3) allows for passage of the brake pressure, set in the mechanical brake-pressure control device (103 3, 5), only in case of a fault in the electrical brake-pressure control device (106 6, 9, 12, 13). The electrical brake-pressure control device (106 6, 9, 12, 13) is thereby accessible to a load-dependent automatic brake-pressure control without the requirement of a load dependent automatic brake-pressure controller in the mechanical brake-pressure control device (103 3, 5).
