NOTICE:
D
Using the wrong fluid can badly damage
brake system parts. For example, just a few
-
drops of mineral based oil, such as engine
oil, in your brake system can damage brake
system parts so badly that they'll have to be
replaced. Don't let someone put in the
wrong kind of fluid.

If you spill brake fluid on your vehicle's
painted surfaces, the paint finish can be
damaged. Be careful not to spill brake fluid
on your vehicle. If you do, wash it off
immediately. See "Appearance Care" in
the Index.

Brake Wear

If you have a C 3500 HD model, it has four
brakes without wear indicators. If you ever hear a brake
rubbing noise, have the brake linings inspected.
If your pickup is not a C 3500 HD model, it has front
disc brakes and rear drum brakes.
Disc brake pads (except C 3500 HD models) have
-
built in wear indicators that make a high
warning sound when the brake pads are worn and new
pads are needed. The sound may come and go or be
heard all the time your vehicle is moving (except when
you are pushing on the brake pedal firmly).
CAUTION:
The brake wear warning sound means that soon
your brakes won't work well. That could lead to
an accident. When you hear the brake wear
warning sound, have your vehicle serviced.
