73-79 Ford F100/f150 Front Disc/Rear Drums Brake Proportion Valve
Our Proportion Valve comes with a 1 year warranty.
 For use on Disc/Drum Setup Only

This 1973-1979 Ford proportioning valve comes with the pigtail wire needed to wire the 2 wires to our one wire pigtail.
This does not affect the operation of the valve. It lights up the brake light in the dash if there is a malfuction.
For trucks that come with the dual wire sensor switch, wire both wires to the supplied single pigtail.

Small modification needed - rear brakeline msy need a brake line reducer or reflaring the line with the correct fitting.

Brake line reducers or adapters are available at many local auto part stores or online at www.brakeconnect.com. 
 

This 1973-1979 Ford F150 brake proportioning valve has a 9/16"-18 connection for Rear Brakes & Dual 3/8"-24 ports for the front brakes.
The connections from the Master Cylinder are 1/2"-20 and 7/16"-24.
This valve comes with a 1 year warranty.
We supply a pigtail for the prop valve wire sensor.
For trucks that have the dual wire sensor switch, wire both wires to the single supplied pigtail. (Note Some Ford trucks may only need the hot wire from the brake light inside the dash.)
A prop valve bleeding tool is in the related items section of this page.

This 1973-1979 Ford F150 brake proportioning valve has one extra port that could be plugged if need be. The new valve has the same mounting holes as the original valve. 

You will need a brake line reducer for the rear brake line fitting. Brake line reducers or adapters are available at many local auto part store or online at www.brakeconnect.com. Search for tread changers.

Called these guys up to check if this was the part I needed. I ordered and it shipped the same day. Excellent part and got the brakes on my 79 working again.

Proportional valve

Review by Keith McGowan from , on 8/8/2022

The part lined up excactly as the instructions showed and was shipped fast

Works as intended

Review by Ryan from , on 3/30/2020

This was the easiest part of my brake system to install. I followed all procedures when installing and bleeding. Even though I had to buy a fitting to fit one of the lines in, it was such a small problem that I didnt even care. Now I have a complete brake system that functions as stock and it functions very well.

The right tool for the job!

This is my second purchase from CCT, my first being for my '85 CJ7, the second for my '67 Ford F250...Both items exceeded my expectations. I am grateful companies like this still exist.
