tem, reducing braking perfor-
mance.
● Clean the filler cap before re-
moving. Use only DOT 4 brake
fl uid from a sealed container.
●
Use only the specified brake
fluid; otherwise, the rubber
seals may deteriorate, causing
leakage.
● Refill with the same type of
brake fl uid. Adding a brake fl u-
id other than DOT 4 may result
in a harmful chemical reaction.
●
Be careful that water does not
enter the brake fluid reser-
voir when refilling. Water will
significantly lower the boiling
point of the fluid and may re-
sult in vapor lock.
NOTICE
Brake fluid may damage painted
surfaces or plastic parts. Always
clean up spilled fl uid immediately.
As the brake pads wear, it is normal
for the brake fluid level to gradually

go down. A low brake fl uid level may
indicate 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
fl uid level goes down suddenly, have
a Yamaha dealer check the cause be-
fore further riding.
