Observe these precautions:
G
When checking the fluid level, make sure the
top of the brake fluid reservoir is level.
G
Use only the designated quality brake fluid.
Otherwise, the rubber seals may deteriorate,
causing leakage and poor brake performance.
Recommended brake fluid: DOT 4
G
Refill with the same type of brake fluid. Mixing
fluids may result in a harmful chemical reaction
and lead to poor brake performance.
G Be careful that water does not enter the brake
fluid reservoir when refilling. Water will signifi-
cantly lower the boiling point of the fluid and
may result in vapor lock.
G
Brake fluid may deteriorate painted surfaces or
plastic parts. Always clean up spilled fluid im-
mediately.
G
Have a Yamaha dealer check the cause if the
brake fluid level goes down.
