1970 Chevelle Disc Brake Hold Off Valve FPR-104D

This valve was used to hold off pressure to the rear brakes so the front brakes would go on a split second before. This was also considered a correction valve for the 1970 model year. During extreme braking conditions, this valve prevented the car from getting sideways and evened out braking loads. This valve is located at the rear of the car, mounted to the back cross member close to where the rubber brake hose attaches through the frame.
