These valves are a reproduction of the original hold-off or correction valves used on 1970 model cars equipped with disc brakes. These valves mount 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.
Authentic reproduction of the original GM product.
