Brake Wear
Your vehicle 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
a CAUTION:
The brake wear warning sound means that soon
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.
See “CaliperKnuckle 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 immediately.
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 brake pads replaced, have the rear
brakes inspected, too.
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 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. The
parking brake
is self-adjusting and no manual
adjustment is required. You may need to have your
brakes inspected more often
if your driving habits or
conditions result in frequent braking.
CaliperKnuckle Maintenance Inspection
If you operate your vehicle in a highly corrosive
environment,
as indicated by the shaded areas on the
map following this text, your vehicle may require
additional brake service. Refer to the appropriate
GM
Service Bulletin for the proper caliper inspection
procedure.
As necessary, caliper pins and knuckle brake
pad abutments should be lubricated at every other tire
rotation. Also, see your
GM dealer's service department
or qualified service center for additional information.
