 Clean the filler cap before re-
moving. Use only DOT 3 or DOT
4 brake fluid from a sealed con-
tainer.
 Use only the specified brake flu-

id; otherwise, the rubber seals
may deteriorate, causing leak-
age.
 Refill with the same type of
brake fluid. Adding a brake fluid
other than DOT 3 or DOT 4 may
result in a harmful chemical re-
action.
 Be careful that water does not
enter the brake fluid reservoir
when refilling. Water will signifi-
cantly lower the boiling point of

the fluid and may result in vapor
lock.
NOTICE
Brake fluid may damage painted
surfaces or plastic parts. Always
clean up spilled fluid immediately.

As the brake pads wear, it is normal for
the brake fluid level to gradually go
down. A low brake fluid level may indi-
cate worn brake pads and/or brake
system leakage; therefore, be sure to
check the brake pads for wear and the
brake system for leakage. If the brake
fluid level goes down suddenly, have a
Yamaha dealer check the cause before
further riding.
