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
i f someone puts in the wrong replacement brake parts.
