My first post to the Forum; I'm a helo driver (so I can read a TM but need pictures) but not a truck guy
so likely to get a few things wrong.
... been digging through the excellent sticky at https://www.steelsoldiers.com/showthread.php?140345-Air-Brake-Info-and-Troubleshooting and other treads but not finding something that is probably a simple thing. I can't get air pressure past the circled valves to trailer (system is charging and holds good pressure on the truck side).
1) I want to know what the valves I have circled in yellow are?
Distribution? Shut-off? (guess 3way ... OFF / pintlel hitch / 5th wheel glad-hand)
--- there are two identical valves (primary blue and emergency red) for the glad-hands but they look to be a 2 or 3 way shut off because they have a hand lever.
--- the valve elbows & fittings are rusted through but no air leak ... I find that odd (M1088 came from Hawaii ... runs/drives fine).
--- I have removed the valves to attempt to buy replacements ... but an online search hasn't revealed anything close.
2) What is stopping air from arriving to this valve? (my guess another valve downstream since there's no airleak here even with dash trailer valve pulled)
3) Can someone please tell me the part name +/or part number and who sells them?

Thanks for giving it a look ... I plan to replace all the lines but first need to move a ROPU trailer on my property so I want this to function.
--- ALSO if there are any Mechanics with LMTV experience in Reno I'd love to hire you ... (there's a motorpool with these down in Carson City so I hope to find someone who can give this truck a proper PMC).
