Brakes

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, have the
brake hydraulic system fixed, since a leak means that
sooner or later the brakes will not work well.
The brake master cylinder
reservoir is filled with
DOT-3 brake fluid. See
Engine Compartment
Overview on page 5-4 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 you have 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. See "Checking Brake Fluid" in this
section.
When the brake fluid falls to a low level, the brake
warning light will come on. See "Brake System Warning
Light" in the owner manual.
Refer to the Maintenance Schedule to determine when
to check the brake fluid. See "Scheduled Maintenance"
in the owner manual.
