Observe these precautions:
8When checking the brake fluid level, make
sure the top of the brake fluid reservoir is
level.
8Use only the designated quality brake fluid,
otherwise, the rubber seals may deteriorate,
causing leakage and poor brake performance.
8Refill with the same type of brake fluid. Mixing
fluids may result in a harmful chemical reac-
tion and lead to poor brake performance.
8Be 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.
8Brake fluid may deteriorate painted surfaces
or plastic parts. Always clean up spilled fluid
immediately.
8Have a Yamaha dealer check the cause if the
brake fluid level goes down.Recommended brake fluid: DOT 4
