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, you
should have the brake hydraulic system fixed, since
a leak means that sooner or later the brakes will
not work well.
5-36
The 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.
So, it is not a good idea to top off the brake fluid.
Adding brake fluid will not correct a leak. If you add
fluid when the linings are worn, there will be too much
fluid when you get new brake linings. 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.
When the brake fluid falls to a low level, the brake
warning light comes on. See Brake System Warning
Light on page 3-41.
