Owner`s manual
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. See “Caliper/Knuckle Maintenance
Inspection”
in
Section
7
of this manual under Part
C
“Periodic Maintenance Inspections.”
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.
Your
rear drum brakes don’t have wear indicators, but
if
you ever hear a rear brake rubbing noise, have the rear
brake
linings
inspected.
Also,
the rear brake drums
should be removed and inspected each time the tires are
removed for rotation or-changing. When you have the
front brakes replaced, have the rear brakes inspected, too.
Brake linings should always be replaced as complete
axle sets.

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 moderate brake stop, your disc
brakes adjust for wear. If you rarely make a moderate or
heavier stop, then your brakes might not adjust correctly.
If you drive in that way, then
--
very carefully
--
make
a
few moderate brake stops about every
1,000
miles
(1
600
km),
so
your brakes will adjust properly.
If
your brake pedal goes down farther than normal, your
rear drum brakes may need adjustment. Adjust them by
backing up and firmly applying the brakes a few times.
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.
Vehicles we design and test have top-quality GM brake
parts in them, as your Buick does when it is new. 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 genuine
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.
