Replacing Brake System Parts
The braking system on a modem 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: Buick, 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 Buick 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.
Batteries have acid that can burn you and gat
that can explode. You can be badly hurt
if you
aren’t careful. See “Jump Starting” in the lndl
for tips on working around a battery without getting hurt.
Contact your dealer to learn how to prepare your vehicle
for longer storage periods.
