Well I have a 931a1 sitting in my drive way, every time I would step on/hold the brakes I had air loss, you could here it from the intake stack, thought it was a brake pot rubber but after checking not be, so started reading TMs which lead to quick release valves, still not to be, then lead to relay valves but not the abs ones, still not to be, at this point the TMs state "if leak is still not fixed notify a supervisor" (yep makes a lot of sense to read the TMs), so now on my own without the tm still looking I found a valve under the front of the engine, checked it sure enough it was my leak (seal ball is broke).

If I had know that was on site, it would have saved me a bunch of time, the m939 air system must have been designed by the same moron that designed the cucv and LMTV electrical systems, every thing goes to a common vent line and there is so much tubing routed like a bunch of spaghetti.
Now, does anybody know what the part number cross over is, I am taking the old one to the truck parts house to try to match it up, guess I need to go though the -p and find this thing and the numbers that go with it.
