<p>A hydraulic vehicle brake system and method of operating same. The system includes an electrohydraulic wheel brake pressure modulation unit, a master brake cylinder (11) which has a pressure medium storage reservoir (12) for hydraulic brake fluid and which can be actuated by means of a brake pedal (9) and to which first and second brake circuits (I, II) are connected. Wheel brakes (3, 4, 5, 6) are connected to the first and second brake circuits (I, II). Each of the first and second brake circuits have a pair of inlets valves (14a-d, 114a-b) and a pair of outlet valves (15a-d, 115a-b) connected to the wheel brakes (3, 4, 5, 6). The outlets of the outlet valves (15a-d, 115a-b) of each of the first and second brake circuits (I, II) are connected to one another by means of jointly used hydraulic line sections (16a, 16b). A safety valve (17a, 117a; 17b, 117b) is provided by means of which an outflow of brake fluid medium out of the line section (16a, 16b) via an outlet port of the safety valves (17a, 117a; 17b, 117b) can be monitored as a means of checking the leak-tightness of the outlet valve and the safety valve.</p> |
