Brakes
Brake Fluid
Your brake master
cylinder reservoir is filled
with DOT-3 brake fluid.
See
Engine Compartment
Overview on page 5-12
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 your brake system fixed, since a leak means that
sooner or later your brakes will not work well, or will
not work at all.
So, it is not a good idea to top off your brake fluid.
Adding brake fluid will not correct a leak. If you add fluid
when your 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.
If the ignition is in ON and the brake fluid is low, the
“Check Brake Fluid” message will be displayed in
the DIC. See “Check Brake Fluid Message” under
DIC Warnings and Messages on page 3-61 .
When your brake fluid falls to a low level, your brake
warning light will come on. See
Brake System Warning
Light on page 3-38 .
