NOTICE:
When using concentrated washer
fluid, follow the manufacturer's
instructions for adding water.
Don't 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 doesn't clean as well as
washer fluid. .
Fill your washer fluid tank only
%
full when it's very cold. This
allows for expansion, which could
damage the tank if it is
completely hll.
Don't use radiator antifreeze in
your windshield washer. It can
damage your washer system and
paint.
Brakes
Brake Master Cylinder
Your brake master cylinder is here. It is
filled with DOT-3 brake fluid.
There are only two reasons why the
brake fluid level in your master cylinder
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. So, it
isn't a good idea to "top off' your brake
fluid. Adding brake fluid won't correct a
leak. If you add fluid when your linings
are worn, then you'll have too much
fluid when you get new brake linings.
You should add (or remove) brake
fluid, as necessary, only when work is
done
W
on the brake hydraulic system.
When your brake fluid falls to a low
level, your brake warning light will
come on. See
Brake System Warning
Light in the Index.
What
to Add
When you do need brake fluid, use only
DOT-3 brake fluid
-
such as Delco
Supreme 11" (GM Part No.1052535).
Use new brake fluid from a sealed
container only, and always clean the
brake fluid reservoir cap before
removing it.
