2000 rd when i bobtail and hit the brakes i have air coming out of my trailer sevice line, and of course my red brake valve is out. When pulling a trailer everything works fine, i was leaning towards a new treadle valve, anybody ever have this problem?

isn't it ran thru the tractor protection valve?

Your right, it seems that any replacement valves don't last nearly as long as original. I think the secret is to try to get new over reman, but I'm not sure.

Might just be just how lucky you are. Let us know how you make out.
