TIPThe rear brake fluid reservoir is located
behind panel A. (See page 6-8.)
WARNING
EWA16000
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 system, reducing
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 does not
enter the brake or clutch fluid
reservoir when refilling. Water will significantly lower the boil-
ing point of the fluid and may re-
sult in vapor lock.
NOTICE
ECA17640
Brake fluid may damage painted sur-
faces or plastic parts. Always clean
up spilled fluid immediately.The brake or clutch fluid reservoir dia-
phragm will lose its shape from the neg-
ative 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 sys-
tem 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 sudden-
ly, have a Yamaha dealer check the
cause before further riding.
