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 rmly.
{CAUTION:
The brake wear warning sound means that
soon the brakes will not 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 rst applied or
lightly applied. This does not mean something is
wrong with the brakes.Properly torqued wheel nuts are necessary to help
prevent brake pulsation. When tires are rotated,
inspect brake pads for wear and evenly tighten
wheel nuts in the proper sequence to GM torque
speci cations.
Rear drum brakes do not 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.
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 brake stop, the brakes
adjust for wear.

When rotating your tires, always use one of the
correct rotation patterns shown here.
If your vehicle has a compact spare tire or a spare
tire that does not match your vehicle’s road tires
and wheels, in size and type, do not include
the spare in the tire rotation.
After the tires have been rotated, adjust the front
and rear in ation pressures as shown on the
Tire and Loading Information label. For the location
of the Tire and Loading Information label see
Loading Your Vehicle on page 286. Make certain
that all wheel nuts are properly tightened, see
“Wheel Nut Torque” underCapacities and
Speci cations on page 430for the proper wheel
nut torque speci cation.
{CAUTION:
Rust or dirt on a wheel, or on the parts to
which it is fastened, can make wheel nuts
become loose after time. The wheel could
come off and cause an accident. When
you change a wheel, remove any rust or
dirt from places where the wheel attaches
to the vehicle. In an emergency, you can
use a cloth or a paper towel to do this;
but be sure to use a scraper or wire brush
later, if needed, to get all the rust or dirt
off. SeeChanging a Flat Tire on page 394.
Any time you rotate the vehicle’s tires the Tire
Pressure Monitor System (TPMS) will need to be
reset. The TPMS identi cation codes will need
to be matched to the tire and wheel position. See
“TPMS Sensor Identi cation Codes” underTire
Pressure Monitor System on page 378.

10. Turn the wheel wrench counterclockwise to
lower the vehicle. Lower the jack completely.
{CAUTION:
Incorrect wheel nuts or improperly
tightened wheel nuts can cause the wheel
to come loose and even come off. This
could lead to an accident. Be sure to use
the correct wheel nuts. If you have to
replace them, be sure to get new GM
original equipment wheel nuts. Stop
somewhere as soon as you can and have
the nuts tightened with a torque wrench to
the proper torque speci cation. See
Capacities and Specifications on page 430
for wheel nut torque speci cation.

Notice:Improperly tightened wheel nuts can
lead to brake pulsation and rotor damage.
To avoid expensive brake repairs, evenly
tighten the wheel nuts in the proper sequence
and to the proper torque speci cation. See
Capacities and Specifications on page 430for
the wheel nut torque speci cation.
11. Tighten the wheel
nuts rmly in a
crisscross sequence
as shown by
turning the wheel
wrench clockwise.When you reinstall the regular wheel and tire, you
must also reinstall the center cap. Place the
cap on the wheel and tap it into place until it seats
ush with the wheel. The cap only goes on one
way. Be sure to line up the tab on the center cap
with the indentation on the wheel.
