Insufficient brake fluid may allow air to
enter the brake system, possibly caus-
ing it to become ineffective.
EAU32341 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
system for leakage.

Observe these precautions:
G When checking the fluid level,
make sure that the top of the mas-
ter cylinder is level by turning the
handlebars.
G
Use only the recommended quality
brake fluid, otherwise the rubber
seals may deteriorate, causing
leakage and poor braking perfor-
1
mance.
Recommended brake fluid:
DOT 3 or 4
G
Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking performance.

G
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.
G
Brake fluid may deteriorate paint-
ed surfaces or plastic parts. Al-
ways clean up spilled
immediately.
G As the brake pads wear, it is nor-
mal for the brake fluid level to grad-
ually go down. However, if the
brake fluid level goes down sud-
denly, have a Yamaha dealer
check the cause.
