Aluminum Brake Proportioning Valve For Disc Vehicle/Truck
The Brake Proportioning Valve is widely used in general Motors of Disc Brake System Vehicles. The 172-1361A Brake Proportioning Valve fits both cars and trucks, such as GM, Ford, Mopar, Universal, etc... It is an Aluminum cast Combination Proportioning Valve. It is a Brake Master Cylinder matched component. The reference OEM number is AC DELCO # 172-1361A. This proportioning valve helps to restrict the amount of pressure sent to the rear brakes under heavy braking, helping prevent the rear brakes from locking up to soon. What differentiates this valve from the adjustable valves and the similar drum brake or disc valve is the metering spring built into the back of the valve. This metering spring helps to slightly "hold off" the drum brakes from engaging right away, keeping the rear brakes from "locking up". If you have 2 wheel drum brakes or 2 wheel disc brakes, let us know at check out and we will send you the correct valve.
Proper operation of your brakes is essential for your safety and the safety of others. Any brake service should be performed ONLY by persons experienced in the installation and proper operation of brake systems. It is the responsibility of the component or kit for the particular application.
DO NOT DRIVE WITH UNTESTED BRAKES!

The most common proportioning valve plumbing is shown. An alternative plumbing method is to plug off the top front line and have the bottom front line go to a "T" fitting. From the "T" fitting, the front lines are then split off to the left and right calipers.
Please note that this valve has:
(1) 9/16-18" port for the rear brakes
(2) 3/8-24" ports for the front left and right calipers
Testing the proportioning valve for proper operation:
1. Use a test light by attaching a clip to a positive contact on the vehicle and the point of the tester to the electrical connection of the combination valve. If the light does not come on, the valve system is operating correctly and no further testing is required.
2. If the light does come on, this indicates that the pressure differential valve is tuck in the front or rear position.
3. Bleed the brake system to determine if the front or rear lines are blocked off. Set up one front wheel and one rear wheel for bleeding at the same time. Crack both bleeder screws and gently pump the pedal a few times. The blocked side will trickle fluid out when the bleeder screw is cracked and the pedal pressed. An unblocked line will squirt fluid out the bleeder.
4. The lines that are clear must be left open and the blocked lines should have the bleeder screws tight to cause pressure to build up on that side. Be sure to use the standard bleeding procedures to prevent air from entering the system.
5. Slowly press the pedal with steady pressure a number of times until the light goes out; this will center the differential valve. You may also hear a pop come from the proportioning valve. This is the metering valve returning to its equalized position. When the light goes out, close the bleeder screw.
