Air Compressor
The air compressor pumps air into the air storage tanks.
It is gear driven by the motor home engine.
Air Tanks
These tanks hold compressed air for the brake system.
They will hold enough air to allow the brakes to be used
several times even if the compressor stops working.
Entrapped liquid is drained automatically from the air
tanks. Consult the Chassis Operator's Manual for addi-
tional information.
Air Dryer
Compressed air usually has some water and compressor
oil in it. This compressed air is cycled through a dryer
to remove air system contaminants. Consult the Chassis
Operator's Manual for additional information.
The Brake Pedal
The harder you push down on the pedal, the more air
pressure is applied to the brakes. When you let up on
the pedal, some of the brake pressure is released. You
will hear the air escape when you let up on the pedal.
As this air is released, the compressor must build the
'pressure back up. Pressing and releasing the pedal
repeatedly can let air out of the system faster than the
compressor can restore it. If the pressure gets too low
and the service brakes will not function properly, the
spring brakes will be applied automatically.
When you push down on the pedal, you will feel both a
spring pressure and the air pressure back against your
foot. With practice, you will know how to judge the
force necessary to stop your motor home.
