Checking the brake fluid level
Front brake
Rear brake
Insufficient brake fluid may allow air to
enter the brake system, possibly caus-
ing it to become ineffective.
Before riding, check that the brake flu-
id is above the minimum level mark
and replenish if necessary. A low
brake fluid level may indicate worn
brake pads and/or brake system leak-
age. 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:
● When checking the fluid level,
make sure that the top of the
brake fluid reservoir is level.
● Use only the recommended qual-
ity brake fluid, otherwise the rub-
ber seals may deteriorate,
causing leakage and poor braking
performance.
● 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 brake fluid reservoir when
refilling. Water will significantly
lower the boiling point of the fluid
and may result in vapor lock.
● Brake fluid may deteriorate paint-
ed surfaces or plastic parts. Al-
ways 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
suddenly, have a Yamaha dealer
check the cause.
