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 malfunc-
tion resulting 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.
original components. Any changes from
the original specifications can af

• Brake linings
• Brake chambers
• Slack adjusters

How to inspect brake pads on disc
brakes
To inspect the brake pads:
1. Park on level ground and chock the
wheels.
2. Temporarily release the parking
brakes.
3. Looking from the ground up at the
bottom of the caliper and rotor,
compare the relative position of two
notches; one located on the caliper
and the other on the carrier.
4. Take a measurement from between
these two notches and compare
MAINTENANCE - Brake System
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
