Valve Pressure Modulator
I have a slow "hissing" leak coming from the "service relay valve". Anyone else ever have this problem? It is located in front of the drive axle about midway. deSanford PS I called Monaco Parts and they can get a new one in about a week. Not sure if you can download the pdf file below, but the unit is in picture #2 in the middle.

Walt beat me to it! Chances are the valve has a tag with manufacturer's part number and any truck parts outlet or truck dealer should have it. Way cheaper than Monaco.

It is not the Inversion Valve, but the Brake System ABS-KB Rear Axle Module by Bendix. I'm going to go back into my e-mail file and send the complete e-mail so maybe the attached picture will be visible. I spent this afternoon with Simple Green under the motor home cleaning it so I can change out the unit. It looks like 3 components attached together. The diaphragm under the center unit is where my leak (slow hiss) is coming from. It will "hiss" for quite a while until all the air is removed from both air tanks. I can drive the rig as the compressor keeps the air pressure up to safe levels. I searched the internet and haven't come up with any info on this unit so far. deSanford

I removed the "attachment" as it wouldn't respond. Now that the parts in question are clean I will see if I can find the part #. Have to wait until the area under the motor home drys.
The above e-mail has the attachment, but I don't think it will work here. Monday when my son AAron comes over I will have him look at this and I'm sure he will be able to post the picture of the unit that is causing the rig to loose air pressure. Sorry thank you all for your patience. deSanford
