Advice re Air System

[Howard O. Truitt]

David,
Have a friend to help let him press the brake while you listen at the wheels to
try and isolate where the leak is. Since you only hear the leak when you depress
the brake pedal it sounds like it would be at the wheel area.

Subject: [WanderlodgeForum] Advice re Air System


Greetings All,
As luck would have it, I encountered my first problem with the air
system on my 89 WB 40 the morning after Rita struck a glancing blow
to east Harris County Texas. I have since been cleaning up the
debris in my yard and discarding all the ruined food which resulted
from an extended power outage and I have not taken any time to start
research on the air problem. Any advice would be appreciated
regarding the following symptoms.

Background: The coach was in a storage building but the system and
suspension were aired up due to my having left the aux air
compressor on in preparation for a possible evacuation. The morning
following the storm I planned to move the coach to my house to take
advantage of the generator and AC. When I started the engine the
system showed to be fully pressurized

Symptoms:
1) When I depressed the brake pedal for the first time, I heard
sounds associated with a large volume of escaping air.

2) The suspension will not dump and the step will not retrack.

3) The Low Air Pressure Alarm will sound after I pump the brake
pedal for a few times.

4) I can not hear any obvious air leaks under the coach after the
system airs up enough (minimum pressure) for the low air pressure
alarm to quit sounding and the aux air compressor is running to
provide additional pressure.

5) The suspension is not leaking down with (the aux air compressor
is turned off) for a couple of days now.

Thanks in advance.
