Servicing Specific Systems And Units
This section will help you keep your Peterbilt vehicle in
good running condition. There are a number of checks
you can do, and you may be able to do some of the ser-
vice work yourself. But please: let your dealer’s service
department do any work you don’t have the tools or skill to
perform. Authorized service mechanics are trained in the
proper technical and safety procedures to fix your Peterbilt
vehicle right.
WARNING! It is dangerous to work on a vehi-
cle without the right know-how and proper
tools. You could be killed or badly injured, and
you could damage the vehicle. Do only work
you know you are fully capable of doing, and
for which you have the right tools.
Brake Adjustment
WARNING! To prevent uncontrolled vehicle
movement and reduce risk of death or per-
sonal injury, park the vehicle on a hard level
surface, apply the parking brake, and chock
all wheels securely.
To operate your vehicle safely and profitably, you need
some understanding of its brake systems. For more on
brakes, see the Index, under Brakes.
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.
CAUTION: The air brake system of this vehicle
was configured for ONE of the following opera-
tions: 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 modifications to the
air brake system in order to retain compliance
with FMVSS 121. Contact your Peterbilt dealer for
instructions.
Once a brake system is set to specifications, changing
any one of its components or any combination of compo-
nents 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 sys-
