BRAKE SYSTEM
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
seemingly 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 together properly,
you could lose control of your vehicle,
which could cause a serious accident.

All vehicle operators should check
their brakes regularly.

WARNING!
Do not use brake linings with a thick-
ness below the specified minimum.
Such linings will have lining rivets
exposed that can damage the brake
drum and reduce brake efficiency,
which could cause death, personal
injury or system failure.

Air Disc Brakes
Have brake pads inspected by a
qualified mechanic for wear at regular
intervals according to the Preventive
Maintenance Schedule on page 5-12.
In severe service or off-highway
applications inspect the linings more
frequently.
Regularly inspect for pad/rotor wear:
•
Park on level ground and chock
the wheels.
•
Temporarily release the parking
brakes.
•
Compare the relative position
of two notches; one located on
the caliper and the other on the
carrier. See the illustration below
to determine if the brakes require
a detailed inspection by a qualified
mechanic.
