YCC-S clutch
1. Minimum level mark
Insufficient brake fluid may allow air to
enter the brake or YCC-S clutch sys-
tems, possibly causing them to become
ineffective.
Before riding, check that the brake fluid
is above the minimum level mark and
replenish if necessary. A low brake fluid
level may indicate worn brake pads
and/or brake system leakage. If the
brake fluid level is low, be sure to check
the brake pads for wear and the brake
system for leakage.
TIP
G The rear brake fluid reservoir is lo-
cated behind panel C. (See page
7-8.)
PERIODIC MAINTENANCE AND ADJUSTMENT
G
The YCC-S clutch fluid reservoir is
located behind panel B. (See page
7-8.)
Observe these precautions:
G When checking the fluid level,
make sure that the top of the brake
and YCC-S clutch fluid reservoirs
are level.
G
Use only the recommended quality
brake fluid, otherwise the rubber
seals may deteriorate, causing
leakage and poor braking or
YCC-S clutch performance.
Recommended brake and YCC-S
clutch fluid:
DOT 4 brake fluid
G
Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking or YCC-S
clutch performance.
G
The brake and YCC-S clutch fluid
reservoir diaphragms will lose their
shape from the negative pressure
if the fluid level goes down too far.
7-24
Be sure to return the diaphragms
to their original shape before rein-
stalling them.
G Be careful that water or dust does
not enter the brake and YCC-S
clutch fluid reservoirs when refill-
ing. Water will significantly lower
the boiling point of the fluid and
may result in vapor lock, and dirt
may clog the ABS hydraulic unit
valves.
G
Brake fluid may deteriorate paint-
ed surfaces or plastic parts. Al-
ways clean up spilled
immediately.
G 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.
