1. Minimum level mark
Insufficient brake fluid may allow air to
enter the brake system, possibly caus-
ing it to become ineffective.
Before riding, check that the brake fluid
is above the minimum level mark and
replenish if necessary. A low brake fluid
level may indicate worn brake pads and/
or brake system leakage. If the brake
fluid level is low, be sure to check the
brake pads for wear and the brake sys-
tem for leakage.
Observe these precautions:
8 When checking the fluid level,
make sure that the top of the mas-
ter cylinder is level by turning the
handlebars.
Use only the recommended qual-
ity brake fluid, otherwise the rub-
ber seals may deteriorate, causing
leakage and poor braking perfor-
mance.
Recommended brake fluid:
DOT 4
8 Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and lead
to poor braking performance.
8 Be careful that water does not en-
ter the master cylinder when refill-
ing. Water will significantly lower the
boiling point of the fluid and may
result in vapor lock.
8 Brake fluid may deteriorate painted
surfaces or plastic parts. Always
clean up spilled fluid immediately.
8 As the brake pads wear, it is nor-
mal for the brake fluid level to
gradually go down. However, if the

Changing the brake fluid
Have a Yamaha dealer change the brake
fluid at the intervals specified in the
NOTE after the periodic maintenance
and lubrication chart. In addition, have
the oil seals of the brake master cylin-
der and caliper as well as the brake hose
replaced at the intervals listed below or
whenever they are damaged or leaking.
8 Oil seals: Replace every two years.
8 Brake hose: Replace every four
years.
brake fluid level goes down sud-
denly, have a Yamaha dealer check
the cause.
