WARNING!
Do not use any replacement part in the
brake system unless it conforms exactly to
original specifications. A nonconforming part
in your vehicle's brake system could cause
a malfunction resulting in an accident caus-
ing death or personal injury. Sizes and types
are so related to one another that a seem-
ingly unimportant change in one may result
in a change in how well the brakes work for
you on the road. If parts do not work togeth-
er properly, you could lose control of your
vehicle, which could cause a serious acci-
dent.
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.

How to inspect brake pads on disc
brakes
Have brake pads inspected by a qualified
mechanic for wear at regular intervals
according to the Preventive Maintenance
Schedule. In severe service or off-highway
applications inspect the linings more
frequently.
To inspect the brake pads:
1. Park on level ground and chock the
wheels.
2. Temporarily release the parking
brakes.
