After reading my air line schematics available on Steel Soldiers and after going to YouTube to view RonMars Air Component Video (which by the way is excellent even after the 4th time) I am turn for help for confirmation.
My parking brakes are taking 20 seconds to fully release. I suspect it is the relay valve since the AntiCompound Valve is first to receive air and then to the Relay Valve/ that would mean that the first point of releasing air is at the Relay Valve.
I did replace both Trailer Valve and Parking Brake Valve because the were leaking air at the stems/ Not particularly a fun job because of the close quarters but done.
The symptoms I have is when Parking brake valve is pushed in calling for release of parking brakes all works well if I apply and drive/ When they are pushed to release and then popped off and then attempt to push right back in it is as hard as a rock and can only be pushed back in and set when held. Now when normally the Parking Brake Valve is pulled out to set the Parking Brakes all works well providing you wait 20 seconds. I have popped the valve and run to the back and felt that air is seeping out of the relay and then at the end of 20 seconds it completes exhaust with a sort of swoosh/
Would it be recommended to pull each line going to the chambers and using shop air apply and release to see if maybe I have a chamber hanging up. (Now that I say it that sounds about right) Or is it most commonly the Relay Valve? I didn't have the help to see if one side releases and not the other or if it is an equal release.
All input is appreciated! By the way does anyone have the Relay Valve number or the Military Number on the Parking Brake Relay Valve which I suspect is the same as the Service Valve Relay. OH RonMar where are you???
