Brakes
Brake Fluid
The brake master cylinder
reservoir is ?lled with
DOT-3 brake ?uid. See
Engine Compartment
Overview on page 5-12 for
the location of the reservoir.
There are only two reasons why the brake ?uid level in
the reservoir might go down:
? The brake ?uid level goes down because of normal
brake lining wear. When new linings are installed,
the ?uid level goes back up.
? A ?uid leak in the brake hydraulic system can also
cause a low ?uid level. Have the brake hydraulic
system ?xed, since a leak means that sooner
or later the brakes will not work well.
Do not top off the brake ?uid. Adding ?uid does not
correct a leak. If ?uid is added when the linings
are worn, there will be too much ?uid when new brake
linings are installed. Add or remove brake ?uid, as
necessary, only when work is done on the brake
hydraulic system.
{ CAUTION:
If too much brake ?uid 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 ?uid only when
work is done on the brake hydraulic system.
See ?Checking Brake Fluid? in this section.
Refer to the Maintenance Schedule to determine when
to check the brake ?uid. See Scheduled Maintenance
on page 6-4.
