L
Rust or dirt on the wheel, or on the parts to
which it is fastened, can make the wheel nuts
become loose after
a time. The wheel could come
off and cause
an accident. When you change a
wheel, remove any rust or dirt from the 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 you need to, to get all the rust or
dirt off.

Never use oil or grease on studs or nuts. If you
do, the nuts might come loose. Your wheel could
fall off, causing
a serious accident.
10. Put on the spare tire. Put the nuts on by hand.
Make sure the cone-shaped end is toward
the
wheel. Tighten each nut by hand until the wheel
is held against the hub. If a nut can’t be turned
by hand, use the extension and see your dealer
as
soon as possible.

Downloaded from www.Manualslib.com manuals search engine 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 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, your disc brakes
adjust for wear.
If 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.
Replacing Brake System Parts
The braking system on a modern vehicle is complex. Its
many parts have to be
of top quality and work well
together if
the vehicle is to have really good braking.
Your vehicle was designed and tested with top-quality
GM brake parts. When you replace parts
of your braking
system
-- for example, when your brake linings wear
down and
you have to have new ones put in -- be sure
you get new approved
GM replacement parts. If you
don’t, your brakes may no longer work properly. For
example,
if someone puts in brake linings that are wrong
for your vehicle, the balance between your front and
rear brakes can change
-- for the worse. The braking
performance you’ve come to expect can change in many
other ways
if someone puts in the wrong replacement
brake parts.
Battery
Every new vehicle has an ACDelco Freedom@ battery.
You never have to add water to one
of these. When it’s
time for a new battery, we recommend an ACDelco
Freedom battery. Get one that has the replacement
number shown on the original battery’s label.

Don’t include the compact spare tire in your
tire rotation.
After the tires have been rotated, adjust the front and
rear inflation pressures as shown on the
Certificationire label. Make certain that all wheel nuts
are properly tightened. See “Wheel Nut Torque” in
the Index.
Rust or dirt on a wheel, or on the parts to which
it
is fastened, can make wheel nuts become loose
after
a 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 you
need to, to get all the rust or dirt
off. (See
“Changing
a Flat Tire” in the Index.) When
It’s Time for New Tires
One way to tell when it’s
time for new tires is to
check the treadwear
indicators, which will
appear when your tires have
only
1/16 inch (1.6 mm) or
less of tread remaining.
You need a new tire if any of the following statements
are true:
0 You can see the indicators at three or more places
around the tire.
0 YOU can see cord or fabric showing through the
tire’s rubber.
The tread or sidewall is cracked, cut or snagged deep
enough to show cord or fabric.
0 The tire has a bump, bulge or split.
0 The tire has a puncture, cut or other damage that
can’t be repaired well because of the size or location
of the damage.
