Brakes
Brake Fluid
The brake master cylinder reservoir
is filled with DOT 3 brake fluid.
See Engine Compartment Overview
on page 5-10 for the location of
the reservoir.
There are only two reasons why the
brake fluid level in the reservoir
might go down:
• The brake fluid level goes down
because of normal brake lining
wear. When new linings are
installed, the fluid level goes
back up.
• A fluid leak in the brake hydraulic
system can also cause a low fluid
level. Have the brake hydraulic
system fixed, since a leak means
that sooner or later the brakes will
not work well.
Do not top off the brake fluid. Adding
fluid does 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 too much brake fluid is added, it
can spill on the engine and burn,
if the engine is hot enough. You
or others could be burned, and
the 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 comes
on. See Brake System Warning
Light on page 3-34.
What to Add
Use only new DOT 3 brake fluid
from a sealed container. See
Recommended Fluids and
Lubricants on page 6-11.
Always clean the brake fluid
reservoir cap and the area around
the cap before removing it. This
helps keep dirt from entering
the reservoir.
