Brake Fluid
The brake master cylinder
reservoir is filled with DOT
3 brake fluid. See Engine
Compartment Overview on
page 5-14 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.
{ CAUTION:
If too much brake fluid is added, it can spill on
the engine and/or fuel operated heater parts, if
equipped. If the vehicle has a diesel engine and a
fuel operated heater, see “Fuel Operated Heater
(FOH)” in the diesel engine supplement. The
fluid will burn if the engine is hot enough. You or
others could be burned, and the vehicle could be
damaged. Add brake fluid only when work is done
on the brake hydraulic system. See “Checking
Brake Fluid” in this section.
Refer to the Maintenance Schedule to determine when
to check the brake fluid. See Scheduled Maintenance
on page 6-4.
