AIR SYSTEM ??

[raypander]

The first thing I would do is walk around the coach with it running and listen
for air leaks. Second, have someone do the walk around for you while you are in
the coach with it running, parking brake released and your foot on the brake
pedal.(any of the brake chambers could be leaking either on the foot brake side
or parking brake side) I'm not sure whether that air compressor is belt driven
or not but if it is, check the belt. Also, you should have a filter that catches
any moisture and "spits" it out. Sometimes that spitter valve leaks but you
should hear the leak on your walk around.
By the way, it should take less than five minutes to build your air up. Also,
if your air pressure drops to around 60 psi while driving your parking brake
will set and lock the brakes. You don't want that to happen! If you have
questions and want to e-mail me direct I will help you in any way I can. I'm not
a mechanic but, Ive owned trucks for almost 35 years so I've learned a little.
