TIP
The rear brake fluid reservoir is located
behind panel C. (See page 7-7.)
Specified brake and clutch fluid:
DOT 4 brake fluid
WARNING
Improper maintenance can result in
loss of braking ability or clutch oper-
ation. Observe these precautions:
 Insufficient brake or clutch fluid
may allow air to enter the brake
or clutch
braking or clutch performance.
 Clean the filler caps before re-
moving. Use only DOT 4 brake
fluid from a sealed container.
 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 4 may result in a
harmful chemical reaction.
 Be careful that water or dust
does not enter the brake or
clutch fluid reservoir when refill-
ing. Water will significantly low-

system, reducing
er the boiling point of the fluid
and may result in vapor lock,
and dirt may clog the ABS hy-
draulic unit valves.
NOTICE
Brake fluid may damage painted
surfaces or plastic parts. Always
clean up spilled fluid immediately.
The brake or clutch fluid reservoir dia-
phragm will lose its shape from the
negative pressure if the fluid level goes
down too far. Be sure to return the dia-
phragm to its original shape before in-
stalling it into the brake or clutch fluid
reservoir.
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. A low clutch
fluid level may indicate clutch system
leakage; therefore, be sure to check
the clutch system for leakage. If the
brake or clutch fluid level goes down
suddenly, have a Yamaha dealer check
the cause before further riding.
