Abstract
PURPOSE: To improve the contruction around a balance lever, which is provided to stride two reducing valves which transmit output oil hydraulic pressure after proportional reduction to left and right rear wheel brakes, thereby improving the safety at the time when a trouble occurs in one of the co-existing systems.
CONSTITUTION: The output oil hydraulic pressure from a master cylinder M is supplied to left and right rear wheel brakes Br1 and Br2 through parallel reducing valves 51 and 52, which transmit the output pressure to the rear wheel brakes Br1 and Br2 after proportional reduction, and also through fluid lines L1 and L2. The salve bodies 9 of both the reducing valves 51 and 52 are tied together by a balancing lever 13. The balancing leve 15 is supplied by srings 15 biasing the valve bodies in the direction of opening valves. A corner portion of the balancing lever 13 facing the inner surface of a housing 12 is made to have a higher hardness than the hardness of the housing inner wall surface. In the even when the balancing lever 13 is greatly titled due to a trouble occurring in one of the system, the lever 13 can thus wedge into the housing inner wall and be locked thereby, so that the braking pressure on in the system can be secured.
