BRAKE SYSTEM
WARNING!
Do not use any replacement part in
the brake system unless it conforms
exactly to original specifications. A
nonconforming part in your vehi-
cle's brake system could cause a
malfunction resulting in an accident
causing death or personal injury.
Sizes and types are so related to
one another that a seemingly unim-
portant 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 acci-
dent.
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.
