In a known tandem master cylinder with a regulator, machining and assembly of the parts is complicated which renders the master cylinder costly. Moreover, such an arrangement is only realizable with master cylinders having a large diameter. There are also functional disadvantages, particularly in the event of failure of one brake circuit, the brake fluid volume consumption of the other brake circuit is materially increased which results in an additional increase of the pedal travel. To avoid these shortcomings, the present invention provides a tandem master cylinder with a regulator including an arrangement, which in the event of failure of the front-axle brake circuit, mechanically actuates the regulator valve coupled to the rear-axle brake circuit by a pressure piston to keep the regulator valve in the open position to enable unreduced braking pressure to be coupled to the rear-axle brake circuit. |
