Abstract
Problems exist in known braking pressure control units for brake systems in which the rear wheels of a vehicle are assigned to different brake circuits. These problems include unequal outlet pressure to the two brake circuits due to manufacturing tolerances and that upon failure of one brake circuit the control function of the intact brake circuit still remains operative. According to the present invention these problems are eliminated by having two differential pistons bear against each other via a common spring device and to provide an arrangement by which upon failure of one brake circuit, the valve of the intact brake circuit will be moved into or kept in an open position.
