Brake fluid level inspection
Insufficient brake fluid may let air enter the
brake system, possibly causing the brakes to
become ineffective.
Before riding, check that the brake fluid is
above the lower level and replenish when
necessary.
1. Minimum level mark
Observe these precautions:
1. When checking the fluid level, make sure
the top of the master cylinder is level by
turning the handlebars.
2. Use only the designated quality brake flu-
id. Otherwise, the rubber seals may dete-
riorate, causing leakage and poor brake
performance.
3. Refill with the same type of brake fluid.
Mixing fluids may result in a harmful
chemical reaction and lead to poor brake
performance.
4. Be careful that water does not enter the
master cylinder when refilling. Water will
significantly lower the boiling point of the
fluid and may result in vapor lock.
5. Brake fluid may deteriorate painted sur-
faces or plastic parts. Always clean up
spilled fluid immediately.
6. Have a Yamaha dealer check the cause
if the brake fluid level goes down.
Recommended brake fluid: DOT 4
