Some driving conditions or climates may cause a brake
squeal when the brakes are first applied or lightly
applied. This does not mean something is wrong with
your brakes.
Properly torqued wheel nuts are necessary to help
prevent brake pulsation. When tires are rotated, inspect
brake pads for wear and evenly torque wheel nuts
in
the
proper sequence
to
GM
specifications.
Brake linings should always be replaced as complete
axle sets.
See “Brake System Inspection” in Section
7
of
this
manual under Part
C
“Periodic Maintenance Inspections.”
Brake Pedal Travel
See your dealer 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
of
brake trouble.
Brake Adjustment
Every time
you
make a brake stop, your disc brakes
adjust for wear.
Replacing Brake System Parts
The braking system
on
a modern 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.
Your vehicle was designed and tested with top-quality
GM brake parts. When you replace parts of your braking
system
--
for example, when your brake linings wear
down and you have to have new
ones
put in
--
be sure
you get new approved
GM
replacement parts. If you
don’t, your brakes may no longer work properly. For
example,
if
someone puts in brake linings that are wrong
for your vehicle, the balance between your front and
rear brakes can change
--
for the worse. The braking
performance you’ve come
to
expect can change in many
other ways
if
someone puts in the wrong replacement
brake parts.
Battery
Every new vehicle has an ACDelco Freedom@ battery.
You never have
to
add water
to
one of these. When it’s
time for a
new
battery,
we
recommend an ACDelco
Freedom battery. Get one that has
the
replacement
number shown on the original battery’s label.
