Some driving conditions or climates
can cause a brake squeal when the
brakes are first applied or lightly
applied. This does not mean
something is wrong with the brakes.
Properly torqued wheel nuts are
necessary to help prevent brake
pulsation. When tires are rotated,
inspect brake pads for wear and
evenly tighten wheel nuts in the
proper sequence to torque
specifications in
Brake linings should always be
replaced as complete axle sets.
See your dealer/retailer if the brake
pedal does not return to normal
height, or if there is a rapid increase
in pedal travel. This could be a
sign that brake service might be
required.
Every time the brakes are applied,
with or without the vehicle moving,
the brakes adjust for wear.
The braking system on a vehicle is
complex. Its many parts have to be
of top quality and work well together
if the vehicle is to have really good
braking. The vehicle was designed
and tested with top-quality brake

parts. When parts of the braking
system are replaced, be sure to get
new, approved replacement parts.
If this is not done, the brakes might

installing disc brake pads that are
wrong for the vehicle, can change

change in many other ways if the
wrong replacement brake parts are
installed.

is filled with DOT 3 brake fluid as
indicated on the reservoir cap.
See
for the location of the
reservoir.
There are only two reasons why the
brake fluid level in the reservoir
might go down:
The brake fluid level goes down
because of normal brake lining
wear. When new linings are
installed, the fluid level goes
back up.
