Brakes
Brake Fluid
Your brake master
cylinder reservoir is
filled with DOT-3 brake
fluid. See
Engine
Compartment Overview
on page 452
for the
location of the reservoir.
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.
So, it is not a good idea to top off your brake fluid.
Adding brake fluid will not correct a leak. If you
add fluid when your linings are worn, then you will
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.
{
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. See “Checking Brake Fluid” in
this section.
When the brake fluid falls to a low level, the brake
warning light will come on. See
Brake System
Warning Light on page 246 .
Refer to the Maintenance Schedule to determine
when to check your brake fluid. See
Scheduled
Maintenance on page 573 .
