M936 unknown part, can anyone identify?

[ClintA]

The brakes don't work very good when this little part went fubar on me, can anyone tell me what it is, and can I plug it off and get by or need to replace? It was located on the frame rail drivers side in between the fuel tank and back tires, it leaks out air only when brakes are applied. There are 2 wires that hook to it too on the BLACK side of the thingamugiggy. Thanks in advance

A civilian one is easy to find but you would need to wire in as it does not have the military packard connectors but a literal fraction of the cost.

I bought two of them on Ebay 2 weeks ago for $16.00 EA.
look up the P/N in the TMs and punch it into Ebay to find it.

So you removed that little thing and went for a drive and found
out the brakes didn't work good w/o it?

It came apart when I was moving the Wrecker, I took it off after it failed. The Wrecker never gets on the highway, so can I just plug it for now?

Yes as long as no road use.
You would have no brake lights.
