Note about GM Proportioning/Combination Valves:
Some 1967-70 cars had a dual master cylinder and were available in front drum/rear drum brakes. 1967 was the first year for disc brakes. If the car has factory front drum brakes, there is a distribution block with a built-in brake warning switch. If the car has factory front disc brakes, it uses the drum distribution block in conjunction with a disc brake hold off valve, which make the disc cars a 2 part valve. For disc brake conversions, the above replacement aftermarket 1 piece proportioning valve is available. This valve will not plumb into existing factory lines.
