Brake Fluid
Your brake master cylinder reservoir is here. It 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.
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.
C A U T b d :
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.
When your brake fluid t'alls to a low level, your brake
warning light will come on. A chime will sound if you
try to drive with this warning light on. See "Brake
System Warning Light" in the Index.
