Chassis Information --- Section 10
The Executive 2005

When preparing to depart, allow the air system to achieve full air pressure as indicated by the air
gauge needles. Listen for the air dryer to purge, indicating that the air dryer is functioning. Look and
listen for abnormalities. Abnormal air pressure readings by either needle of the air gauge alerts the
operator to have the air system checked to avoid an untimely failure.
Should a failure occur in the air system, preventing the air pressure from building, it may
become necessary to “cage” the spring brakes. This is an emergency procedure only. Caging the rear
air brake chambers manually overrides the spring brakes and allows the vehicle to move. This proce-
dure does not affect normal service braking.
NOTE:
When the park brake is released, the Park illumination lamp will remain lit until air
system pressure is above 65 psi.

ARNING:
When parked, if the air tank is not depleted, there is the possibility of an accidental
release of the parking brake. Traveling with small children and/or pets may require a
small block to be fabricated to prevent accidental release. The block should be placed
under the knob on the dash panel. A wooden clothes pin, clasped at the base of the shaft,
will work.
Brake Adjustment/Slack Adjuster
The motorhome is equipped with automatic slack adjusters. As brake lining wears, the slack
adjusters will automatically ratchet on the return stroke as needed. This ratchet action will keep the
brake lining at proper adjustment. Brake adjustment should not be necessary. Automatic slack
adjusters and the connecting S-cam shaft require periodic lubrication and inspection.
NOTE:
Replacement parts should be of the same original equipment size and type. Mixing
brake components may result in unequal braking action. Brake adjustments are part of
normal maintenance of the motorhome. Brake adjustments are not covered by the
manufacturer.
WARNING:
Brake lining may contain asbestos material and should only be serviced by quali-
fied service technicians who are trained in the appropriate precautionary procedures.
If any loss of braking effectiveness or abnormal braking indications are noticed, the
brakes and slack adjusters should be inspected by a qualified brake technician.
