ABSTRACT:
A braking pressure control unit for use on vehicles provides for dual-circuit braking of the rear axle. The braking pressure control unit comprises a braking force reducer including a stepped piston and a braking force limiter disposed coaxially and in series therewith. The closing member of the limiter bears directly against the stepped piston while the closing member of the reducer bears, in the rest position, against a stop independent of the limiter. As a result, the change-over point in one brake circuit will not change in the event of failure of the other brake circuit.
