Abstract
An improved wheel lock prevention device for use in the brake system of motor vehicles. The device has a relay valve included in assembly with a motor vehicle operator controlled brake velve, a wheel brake cylinder and a source of pressurized air. The relay valve has a primary and secondary pressure side. The primary pressure side is connected to the brake valve and the secondary side is connected to the wheel brake cylinder. A short circuit connection between the primary and secondary pressure sides is provided with a control for effecting a balancing of the pressures on both the primary and secondary pressure sides after the pressure on both sides has been reduced from a peak value by a desired extent during application of the brake system.
