Brake Fluid - GMC 2000 Sonoma Owner's Manual

NOTICE:
D
When using concentrated washer fluid,
follow the manufacturer's instructions for
adding water.
D
Don't mix water with ready
fluid. Water can cause the solution to freeze
and damage your washer fluid tank and
other parts of the washer system. Also,
water doesn't clean as well as washer fluid.
D
Fill your washer fluid tank only
-
three quarters full when it's very cold.
This allows for expansion if freezing occurs,
which could damage the tank if it is
completely full.
D
Don't use engine coolant (antifreeze) in
your windshield washer. It can damage
your washer system and paint.

Brakes

Brake Fluid

Your brake master cylinder reservoir is filled with
-
DOT 3 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 won't work well, or won't work at all.
