In a known tandem master cylinder with two regulators for use in vehicles using diagonally split brake circuits, machining and assembly of the components is time consuming which makes the device expensive to manufacture. Moreover, the arrangement is only realizable with master cylinders having a relatively large diameter. There are also functional disadvantages, particularly that in the event of failure of a brake circuit the fluid volume consumption of the other brake circuit is materially increased which further increases the brake pedal travel. To eliminate these shortcomings, the tandem master cylinder with two regulators of the present invention includes means which, in the event of failure of a brake circuit, the regulator valve of the other brake circuit is actuated mechanically by one of the pressure pistons so that the regulator valve of the intact brake circuit is kept open to enable unreduced braking pressure to be coupled to the intact brake circuit. |
