Brakes
Brake Fluid
The brake master cylinder
reservoir is filled with
DOT 3 brake fluid. See
Engine Compartment
Overview on page 6-14
for the location of the
reservoir.
There are only two reasons why the brake fluid level in
the reservoir might go down:
• The brake fluid level goes down because of normal
brake lining wear. When new linings are installed,
the fluid level goes back up.
• A fluid leak in the brake hydraulic system can also
cause a low fluid level. Have the brake hydraulic
system fixed, since a leak means that sooner
or later the brakes will not work well.
Do not top off the brake fluid. Adding fluid does 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.
