Proportion Valve: How it works

A while ago I pulled my drum brakes from the front of my 1975 Ford Bronco and installed disc brakes but I never replaced the proportioning valve. Then when I was removing my factory wiring harness I broke the connector that feeds the brake warning light. So I figured it was time for a new proportioning valve for this Early Bronco.

This is what I bought: https://tomsoffroad.com/parts/66-77-ford-bronco-disc-brake-proportioning-valve-kit

One of the things that I found when I was getting the proportioning valve was the proportioning valve tool. It was like $6 and it screws into the top of the proportioning valve where the brake warning light switch is. The nub at the end of the tool prevents the pressure differential switch in the prop valve from tripping when you bleed the brakes. Great little tool, make sure to get it too!
