Abstract
A device of the type adapted to be interposed between rear wheel brakes of a vehicle and one of dual master cylinders for separate hydraulic circuits to the front and the rear brakes, for not only sensing axle loading and weight shift in order to optimize braking effectiveness but also permitting unrestrained passage of fluid therethrough for the purpose of compensating an accidental failure of the front brakes. The device is characterized by the fact that a load sensing spring is provided for sensing the varying load on vehicle wheels in a manner such that the load sensing spring is rather less loaded in case of the failure of the front brakes than is experienced prior to the failure.
