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 service
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.
Brake Adjustment
WARNING! To prevent uncontrolled vehicle
movement and reduce risk of personal 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.
WARNING! It is dangerous to work on a vehicle
without the right know-how and proper tools.
