YCC-S clutch This model is equipped with a hydraulic
clutch, therefore, it is necessary to
check the YCC-S clutch fluid level and
check the hydraulic system for leakage
before each ride. If the YCC-S clutch
plates wear out, shifting becomes
rough or clutch slippage will occur,
causing poor acceleration. If any of the
above occurs, have a Yamaha dealer
check the YCC-S clutch.
EAU36501
Rear brake light switch The rear brake light switch, which is ac-
tivated by the brake pedal, is properly
adjusted when the brake light comes
on just before braking takes effect. If
necessary, have a Yamaha dealer ad-
just the brake light switch.
EAU22390
Checking the front and rear
brake pads The front and rear brake pads must be
checked for wear at the intervals spec-
ified in the periodic maintenance and
lubrication chart.
EAU43431
Front brake pads
The front brake calipers are equipped
with two sets of brake pads.
Each front brake pad is provided with a
wear indicator groove, which allows
you to check the brake pad wear with-
out having to disassemble the brake.
To check a brake pad for wear, check
its wear indicator groove. If a brake pad
has worn to the point that the wear indi-1. Brake pad wear indicator groove

have a Yamaha dealer replace the
brake pads as a set.
EAU22500
Rear brake pads
Check each rear brake pad for damage
and measure the lining thickness. If a
brake pad is damaged or if the lining
thickness is less than 0.8 mm (0.03 in),
have a Yamaha dealer replace the
brake pads as a set.
EAU40591
Checking the brake and
YCC-S clutch fluid levels Front brake
Rear brakeYCC-S clutch
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.
NOTE:

The rear brake fluid reservoir is lo-
cated behind panel C. (See page
6-7.)

The YCC-S clutch fluid reservoir is
located behind panel B. (See page6-7.)
Observe these precautions:


When checking the fluid level,
make sure that the top of the brake
and YCC-S clutch fluid reservoirs
are level.


Use only the recommended quality
brake fluid, otherwise the rubber
seals may deteriorate, causing
leakage and poor braking or
YCC-S 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 YCC-S
clutch performance.


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.Be sure to return the diaphragms
to their original shape before rein-
stalling them.


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.


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.
EAU40600
Changing the brake and
YCC-S clutch fluids Have a Yamaha dealer change the
brake and YCC-S clutch fluids at the in-
tervals specified in the NOTE after the
periodic maintenance and lubrication
chart. In addition, have the oil seals of
the brake and YCC-S clutch master cyl-
inders and calipers as well as the brake
and YCC-S clutch hoses replaced at
the intervals listed below or whenever
they are damaged or leaking.

Oil seals: Replace every two
years.


Brake and YCC-S clutch hoses:
Replace every four years.
Recommended brake and YCC-S
clutch fluid:
DOT 4 brake fluid
