Inspecting the brake fluid
level
Insufficient brake fluid may let air
enter the brake system, possibly
causing the brakes to become inef-
fective.
Before riding, check that the brake
fluid is above the minimum level
and fill when necessary.
Observe these precautions:

When checking the fluid level,
make sure the top of the mas-
ter cylinder is level by turning
the handlebars.

Minimum level mark
8
Use only the designated quali-
ty brake fluid. Otherwise, the
rubber seals may deteriorate,
causing leakage and poor
brake performance.
NOTE:
If DOT 4 is not available, DOT 3 can
be used.
8
Refill with the same type of
brake fluid. Mixing fluids may
result in a harmful chemical
reaction and lead to poor
brake performance.
8
Be careful that water does not
enter the master cylinder when
refilling. Water will significant-
ly lower the boiling point of
the fluid and may result in
vapor lock.
Recommended brake fluid:
DOT 4

Brake fluid may deteriorate
painted surfaces or plastic
parts. Always clean up spilled
fluid immediately.

Have a Yamaha dealer check
the cause if the brake fluid
level goes down.
