This valve is a reproduction of the original hold-off or correction valve used on 1970 model cars equipped with disc brakes. The valve mounting to the frame and holds pressure from the rear allowing the front brakes to actuate a split second prior to the rears. During extreme braking, the valve prevents the car from getting sideways as well as evening out the braking load.
