WARNING
Improper maintenance can result in loss
of braking ability. Observe these precau-
tions:
Insufficient brake fluid may allow air to
G
enter the brake system, reducing brak-
ing performance.
Clean the filler cap before removing. Use
G
only DOT 4 brake fluid from a sealed
container.
Use only the specified brake fluid; other-
G
wise, the rubber seals may deteriorate,
causing leakage.
Refill with the same type of brake fluid.
G
Adding a brake fluid other than DOT 4
may result in a harmful chemical reac-
tion.
Be careful that water does not enter the
G
brake fluid reservoir when refilling. Wa-
ter will significantly 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 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 fluid
level goes down suddenly, have a Yamaha
dealer check the cause before further riding.
