Brakes; Brake Fluid - GMC Sierra Denali 2006 Owner's Manual

Notice:
•
When using concentrated washer fluid, follow
the manufacturer's instructions for adding
water.
•
Do not mix water with ready-to-use washer fluid.
Water can cause the solution to freeze and
damage your washer fluid tank and other parts
of the washer system. Also, water does not
clean as well as washer fluid.
•
Fill your washer fluid tank only three-quarters
full when it is very cold. This allows for
expansion if freezing occurs, which could
damage the tank if it is completely full.
•
Do not use engine coolant (antifreeze) in your
windshield washer. It can damage your washer
system and paint.
Open the cap with the
washer symbol on it. Add
washer fluid until the
tank is full. See Engine
Compartment Overview on
page 5-10 for reservoir
location.

Brakes

Brake Fluid

There are only two reasons why the brake fluid level in
the reservoir might go down. The first is that the brake
fluid goes down to an acceptable level during normal
brake lining wear. When new linings are put in, the fluid
level goes back up. The other reason is that fluid is
leaking out of the brake system. If it is, you should have
your brake system fixed, since a leak means that sooner
or later your brakes will not work well, or will not
work at all.
Your brake master cylinder
reservoir is filled with
DOT-3 brake fluid. See
Engine Compartment
Overview on page 5-10 for
the location of the
reservoir.
