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 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.
A
CAUTION:
-
If you have too much brake fluid, it can spill
on the engine. The fluid will burn if the engine
is hot enough. You or others could be burned,
and your vehicle could be damaged. Add brake
fluid only when work is done on the brake
hydraulic system.
I A
CAUTIC'J:
With the wrong kind of fluid in your brake
system, your brakes may not work well, or they
may not even work at all. This could cause a
crash. Always use the proper brake fluid.
