ABSTRACT:
A vehicular hydraulic brake system wherein valve means are provided which in the release position of the brake and during normal braking actions establish communication between diagonally opposite wheel brakes and which preferably hydraulically connect the wheel brakes of the rear axle of the automotive vehicle with each other. In order to achieve a higher degree of operational safety a change-over valve which is controllable by the pressure prevailing in the pressure chamber of the hydraulic power booster is connected at each wheel brake of the rear axle. Each change-over valve connects diagonally opposite wheel brakes with each other in a first position and, upon pressurization, interrupts this communication and establishes a communication between two wheel brakes of one vehicle axle.
