Brakes
Brake Fluid
The master cylinder
reservoir is filled with
DOT-3 brake fluid. See
Engine Compartment
Overview on page 258
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 the
brake system fixed, since a leak means that
sooner or later the brakes will not work well, or
will not work at all.
So, it is not a good idea to top off the brake fluid.
Adding brake fluid will not correct a leak. If you
add fluid when the 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 your vehicle has 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 the brake fluid falls to a low level, the brake
warning light will come on. See
Brake System
Warning Light on page 168 .
