●
When checking the fluid level,
make sure that the top of the brake
or clutch fluid reservoir is level.
●
Use only the recommended quality
brake fluid, otherwise the rubber
seals may deteriorate, causing
leakage and poor braking or clutch
performance.
●
Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking or clutch per-
formance.
● The brake or clutch fluid reservoir
diaphragm will lose its shape from
the negative pressure if the fluid
level goes down too far. Be sure to
return the diaphragm to its original
shape before installing it into the
brake or clutch fluid reservoir.
●
Be careful that water does not en-
ter the brake or clutch fluid reser-
voir 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 grad-
ually go down. However, if the
brake fluid level goes down sud-
denly, have a Yamaha dealer
check the cause.
