Periodic maintenance and adjustment
7-22

z A low brake fluid level may indi-
cate worn brake pads or brake
system leakage; therefore, be sure
to check the brake pads for wear
and the brake system for leakage.
z If the brake fluid level goes down
suddenly, have a Yamaha dealer
check the cause before further rid-
ing.
WARNING
EWA15991
Improper maintenance can result in
loss of braking ability. Observe
these precautions:
z Insufficient brake fluid may al-
low air to enter the brake sys-
tem, reducing braking
performance.
z Clean the filler cap before re-
moving. Use only DOT 4 brake
fluid from a sealed container.
z Use only the specified brake flu-
id; otherwise, the rubber seals
may deteriorate, causing leak-
age.
z Refill with the same type of
brake fluid. Adding a brake fluid
other than DOT 4 may result in a
harmful chemical reaction.
z 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.
EAU22734
Changing the brake fluid
Have a Yamaha dealer change the
brake fluid every 2 years. In addition,
have the seals of the master cylinders
and brake calipers, as well as the brake
hoses replaced at the intervals listed
below or sooner if they are damaged or
leaking.
z Brake seals: every 2 years
z Brake hoses: every 4 years
