Checking the front brake fluid
level
ZAUM00**
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:
• When checking the fluid level,
6-16
EAU32343 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
• Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and lead
to poor braking performance.
• 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.
• Brake fluid may deteriorate painted
surfaces or plastic parts. Always
clean up spilled fluid immediately.
• As the brake pads wear, it is nor-
mal for the brake fluid level to
gradually go down. However, if the
brake fluid level goes down sud-
denly, have a Yamaha dealer check
the cause.
