Battery; Replacing Brake System Parts - Pontiac Sunfire 2003 Owner's Manual

Brake Adjustment
Every time you make a moderate brake stop, your disc
brakes adjust for wear. If you rarely make a moderate
or heavier stop, then your brakes might not adjust
correctly. If you drive in that way, then — very
carefully — make a few moderate brake stops about
every 1,000 miles (1 600 km), so your brakes will adjust
properly.
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 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 need new ones put in — be sure
you get new approved GM replacement parts. If you do
not, 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 have come to expect can
change in many other ways if someone puts in
the wrong replacement brake parts.

Battery

Your new vehicle comes with a maintenance free
®
ACDelco battery. When it's time for a new battery, get
one that has the replacement number shown on the
original battery's label. We recommend an ACDelco
battery. See Engine Compartment Overview on
page 5-12 for battery location.
Warning: Battery posts, terminals and related
accessories contain lead and lead compounds,
chemicals known to the State of California to cause
cancer and reproductive harm. Wash hands after
handling.
