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).
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.
I 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.
Free movement 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 any 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.
