10-24 Vehicle Care
There are only two reasons why the
fluid level in the reservoir might
go down:
The 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/clutch
hydraulic system can also cause
a low fluid level. Have the brake/
clutch hydraulic system fixed,
since a leak means that sooner
or later the brakes will not
work well.
Do not top off the brake/clutch 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 fluid, as
necessary, only when work is done
on the brake/clutch hydraulic
system.
Warning
If too much brake fluid is added, it
can spill on the engine and 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/clutch
hydraulic system.
When the brake fluid falls to a low
level, the brake warning light comes
on. See Brake System Warning
Light on page 5-16.
What to Add
If the vehicle has DOT 3 brake fluid,
as indicated on the reservoir cap,
use only new DOT 3 brake fluid from
a sealed container. See
Recommended Fluids and
Lubricants on page 11-11.
If the vehicle has DOT 4 brake fluid,
as indicated on the reservoir cap,
use only new DOT 4 brake fluid from
a sealed container. See
Recommended Fluids and
Lubricants on page 11-11.
It is recommended that the brake/
clutch hydraulic system be flushed
and refilled with new fluid at a
regular maintenance service
interval. See Maintenance Schedule
on page 11-2. Always clean the
brake/clutch fluid reservoir cap and
the area around the cap before
removing it. This helps keep dirt
from entering the reservoir.
