ABSTRACT:
In a method of controlling the brake pressure in the rear wheel brakes of a double-track vehicle, wherein the rotational speeds at least of the rear wheels are measured and the brake pressure is lowered, kept constant, or raised, depending on the unstable or stable states arising at the individual rear wheels, the pressure in the brake of a stable rear wheel being approximated at least temporarily to the pressure in the brake of an unstable rear wheel, it is provided that, upon initiating a pressure decrease in the brake of an unstable rear wheel, the pressure in the brake of the stable rear wheel is kept constant for a predetermined period of time (.DELTA.t) and then decreased until the pressure in the brake of the unstable wheel is either kept constant or increased. This guarantees shorter stopping distances and at the same time provides a smaller difference in the braking torques at the rear axle, at good stability of the motor vehicle.
