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 reservoir 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.
