Battery; Brake Adjustment - GMC Sierra 2008 Owner's Manual

Brake Pedal Travel
See your dealer/retailer 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 that brake service
might be required.

Brake Adjustment

Every time you make a brake stop, the brakes adjust
for wear.
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
brake parts. When you replace parts of the braking
system — for example, when the brake linings
wear down and you need new ones put in — be sure
you get new approved replacement parts. If you
do not, the brakes might not work properly.
For example, if someone puts in brake linings that
are wrong for your vehicle, the balance between the
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 vehicle has a maintenance free battery
(or batteries). When it is time for a new battery,
see your dealer/retailer for one that has the
replacement number shown on the original battery's
label. See Engine Compartment Overview on page 5-16
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.
