change time CHEVROLET ASTRO 1996 User Guide

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 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.
Vehicles we design and test have top-quality
GM brake
parts
in them, as your vehicle does when it is new. 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 genuine 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 a Delco Freedom@ battery. You
never have
to add water to one of these. When it’s time
for a new battery, we recommend a Delco Freedom
battery. Get one that has the replacement number shown
on
the original battery’s label.

Tire Inspection and Rotation
Tires should be inspected every 6,000 to 8,000 miles
(10 000 to 13 000 km) for any signs of unusual wear.
If unusual wear is present, rotate your tires as soon as
possible and check wheel alignment. Also check for
damaged tires or wheels. See “When It’s Time for New
Tires” and “Wheel Replacement” later in this section for
more information.
The purpose of regular rotation
is to achieve more
uniform wear for all tires on the vehicle. The first
rotation is the most important. See “Scheduled
Maintenance Services” in the Index for scheduled
rotation intervals. When
rotating your tires, always use the correct rotation
pattern shown here.
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
CertificatiodTire label. Make certain that all wheel nuts
are properly tightened. See “Wheel
Nut Torque” in
the Index.
’ A CAUTIO1
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.)
