Brakes
Brake Fluid
Your master cylinder reservoir is on the driver's side of
the engine compartment. It is filled with DOT-3 brake
fluid. See Engine Compartment Overview on page 5-12.
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 won't work well, or won't
work at all.
So, it isn't a good idea to "top off' your brake fluid.
Adding brake fluid won't correct a leak. If you add
fluid when your linings are worn, then you'll 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.

When your brake fluid falls to a low level, your brake
warning light will come on. A chime will sound if you try
to drive with this warning light on. See Brake System
