Brake Fluid
The brake master cylinder
reservoir is filled with
DOT-3 brake fluid. See
Engine Compartment
Overview on page 5-11 for
reservoir location and
access.
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.
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.
If the ignition is on and the brake fluid is low, the
CHECK BRAKE FLUID message will be displayed in
the Driver Information Center (DIC). See DIC Warnings
and Messages on page 3-80.
