1999 Contessa Magnum B-Series Air Bag Ride Height Settings

<< < (3/3)

Mike the air governor should be mounted to the side of the compressor or possibly remote mounted with smaller air lines connecting it to the compressor.
It looks like this.

The air dryer should be mounted on the passenger side out board of the frame rails to the rear of the battery compartment.
There should be a braided stainless air line about as big around as your thumb which runs from the compressor to the dryer.

Mike Gineris:
There is no Air Dryer installed on my coach.  Still searching for source of air leak.

Eric Maclean Co-Admin:
Mike
Does you coach have air over hydraulic brakes or is it hydraulic assist using the power steering pump for power assist?
It's been my experience that some of the coaches which only used air for ride height.  Ie ( no air brakes) didn't have an air dryer.

Mike Gineris:
I didn't even know that was a thing.  I do have hydraulic assist using the power steering pump for power assist.  I inspected and found the line running to the brake from the Power Steering.  I'm guessing that's evidence enough?  I still have air powered parking brakes and an alarm that sounds.  I ran up the pressure and turned off the Engine then turned the key on to pump the brake and bring down the pressure but there was no pressure decrease when I pressed the brake pedal.  I feel that's evidence enough.  The air leak(s) have been found and I only have one pesky compression fitting at a Haldex valve that still allows 10 psi drop over 10 hours but I think I'm OK with that.

I almost feel good that I don't have Air Brakes and the system is much less complex.  I don't know if my feelings are misguided.

I very much value your responses Eric.  Thank you!
