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).
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.
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 Trave/
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.
Tf 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.

Wheel Replacement
Replace any wheel that is bent, cracked or badly rusted. If wheel nuts keep
coming loose, the wheel, wheel bolts, and wheel nuts should be replaced.
If
the wheel leaks air, replace it (except some aluminum wheels, which can
sometimes be repaired). See your GM dealer if any
of these conditions exist.
Your dealer will know the kind
of wheel you need.
Each new wheel should have the same load carrying capacity, diameter,
width, offset, and be mounted the same way as the one it replaces.
If you need to replace any of your wheels, wheel bolts, or wheel nuts,
replace them only with new GM original equipment parts. This way, you
will be sure to have the right wheel, wheel bolts, and wheel nuts
for your
GM model.
NOTICE:
The wrong wheel can also cause problems with bearing life,
brake cooling, speedometer/odometer calibration, headlight aim, bumper height, vehicle ground clearance, and tire or tire chain\

clearance to the body and chassis.
