CAUTION
The air brake system of this vehicle
was configured for ONE of the follow-
ing operations: tractor or truck, and
complies with the respective portions
of FMVSS 121. A tractor shall not be
operated or configured as a truck, nor
shall a truck be operated or configured
as a tractor, without significant modifi-
cations to the air brake system in order
to retain compliance with FMVSS 121.
Contact your dealer for instructions.
WARNING
Do not use brake linings with a thick-
ness below the specified minimum.
Such linings will have lining rivets ex-
posed that can damage the brake
drum and reduce brake efficiency,
which could cause death, personal in-
jury or system failure.
WARNING
Do not use any replacement part in the
brake system unless it conforms ex-
actly to original specifications. A non-
conforming part in your vehicle's brake
system could cause a malfunction re-
sulting in an accident causing death or
personal injury. Sizes and types are so
related to one another that a seeming-
ly unimportant change in one may re-
sult in a change in how well the brakes
work for you on the road. If parts do
not work together properly, you could
lose control of your vehicle, which
could cause a serious accident.
Brake adjustment and brake balance must
be set carefully to (1) make the most
efficient use of the forces available for
braking and (2) allow equal stopping forces
at all wheels. Once a brake system is set
to specifications, changing any one of its
components or any combination of
components may cause the system to not
work as well. All parts have to work
together to perform as they should. Any
replacement components in your brake
system should be exactly equal to the
original components. Any changes from
the original specifications can affect the
whole system. All of the following areas are
interrelated and must conform to original
specifications:
• Tire Size
• Drum brakes
• Cam Radius
• Wedge Angle
• Drum Radius
• Brake Linings
• Brake Chambers
• Slack Adjusters
• Disc Brakes
• Disc Rotors
All vehicle operators should check their
brakes regularly.
