The brake and YCC-S clutch fluid res-
ervoir diaphragms will lose their shape
from the negative pressure if the fluid
level goes down too far. Be sure to re-
turn the diaphragms to their original
shape before reinstalling them.
As the brake pads wear, it is normal for
the brake fluid level to gradually go
down. A low brake fluid level may indi-
cate worn brake pads and/or brake
system leakage; therefore, be sure to
check the brake pads for wear and the
brake system for leakage. A low
YCC-S clutch fluid level may indicate
YCC-S clutch system leakage; there-
fore, be sure to check the YCC-S
clutch system for leakage. If the brake
or YCC-S clutch fluid level goes down
suddenly, have a Yamaha dealer check
the cause before further riding.

Have a Yamaha dealer change the
brake and YCC-S clutch fluids at the
intervals specified in the periodic main-

calipers as well as the brake and
YCC-S clutch hoses replaced at the in-
tervals listed below or whenever they
are damaged or leaking.
Oil seals: Replace every two
years.
Brake and YCC-S clutch hoses:
