brake CHEVROLET TRACKER 1993 Repair Manual

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 Geo 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 Geo 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
catalog number shown on the original
battery’s label.
Vehicle Storage
If you’re not going to drive your vehicle
for
25 days or more, take off the black,
negative
(-) cable from the battery.
This will help keep your battery from
running down.
