Fantastic video. Your instructions made a very complicated valve easy to understand how it operates. Thankyou. It's always been a mystery how these things worked until I watched this video.

I have no air leaks But when I apply the brakes It drops from 120 to 90 If I apply them again it drops from 90 to 60 Could this foot valve be my problem?
