Brake Wear
Your Buick has front disc brakes and rear drum brakes.
Disc brake pads have built-in wear indicators that make a
high-pitched warning sound when the brake pads are worn
and new pads are needed.
The sound may come and go or
be heard all
the time your vehicle is moving (except when
you are pushing on the brake pedal firmly).
A CAUTION:
The brake wear warning sound means that
sooner or later your brakes won’t work well.
That could lead to an accident. When you hear
the brake wear warning sound, have your
vehicle serviced.
NOTICE:
Continuing to drive with worn-out brake pads
could result in costly brake repair.
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.
Fre’- -1ovement
of brake calipers and properly torqued
wheel nuts are necessary to help prevent brake
pulsation. When tires are rotated, inspect brake calipers
for movement, 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 apply the brakes, with or without the
vehicle moving, your brakes adjust for wear.

Part C: Periodic Maintenance
Inspections
Listed below are inspections and services which should
be performed
at least twice a year (for instance, each
spring and fall). You should
let your GM dealer’s
service department or other qualified service center do
these jobs. Make sure an.y necessary repairs are
completed at once.
Proper procedures to perform these services may be
found in a Buick Service Manual. See “Service and
Owner Publications” in the Index.
Steering, Suspension and Front- Wheel-Drive
Axle Boot and Seal Inspection
Inspect the front and rear suspension and steering
system for damaged, loose or missing parts, signs of
wear or lack of lubrication. Inspect the power steering
lines and hoses for proper hook-up, binding, leaks,
cracks, chafing, etc. Clean and then inspect the drive
axle boot seals for damage, tears or leakage. Replace
seals if necessary.
Exhaust System Inspection
Inspect the complete exhaust system. Inspect the body near
the exhaust system.
Look for broken, damaged, missing or out-of-position parts as well
as open seams, holes, loose
connections or other conditions which could cause a
heat
build-up in the floor pan or could let exhaust fumes into
the vehicle. See “Engine Exhaust” in the Index.
Radiator and Heater Hose Inspection
Inspect the hoses and have them replaced if they are
cracked, swollen or deteriorated. Inspect all pipes,
fittings and clamps; replace as needed.
Throttle Linkage Inspection
Inspect the throttle linkage for interference or binding,
and for damage or missing parts. Replace parts
as
needed. Replace any cables that have high effort or
excessive wear.
Do not lubricate accelerator and cruise
control cables.
Brake System Inspection
Inspect the complete system. Inspect brake lines and
hoses for proper hook-up, binding, leaks, cracks,
chafing, etc. Inspect disc brake pads for wear and rotors
for surface condition. Also inspect drum brake linings
for wear and cracks. Inspect other brake parts, including
drums, wheel cylinders, calipers, parking brake, etc.
Check parking brake adjustment. You may need to have
your brakes inspected more often if your driving habits
or conditions result in frequent braking.
