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 hydraulic system. If it is, you
should have the brake hydraulic system fixed, since
a leak means that sooner or later the brakes will
not work well.
The master cylinder
reservoir is filled with
DOT-3 brake fluid.
See Engine Compartment
Overview on page 5-12
for the location of the
reservoir.
It is not a good idea to top off the brake fluid. Adding
brake fluid will not correct a leak. If fluid is added when
the linings are worn, there will be too much fluid when
new brake linings are installed. 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 3-31.
