YCC-S clutch
This model is equipped with a hydrau-
lic clutch, therefore, it is necessary to
check the YCC-S clutch fluid level and
check the hydraulic system for leak-
age. (See page 6-25.)
TIP
If shifting becomes rough or clutch
slippage occurs, or if you notice poor
acceleration or engine stalls, have a
Yamaha dealer check the clutch for wear.

Checkin g the brake lever free
play
There should be no free play at the
brake lever end. If there is free play,
have a Yamaha dealer inspect the
brake system.
WARNING
EWA14212
A soft or spon gy feelin g in the b rake
lever can in dicate the presence of
air in the hy draulic system. If there is
air in the hy draulic system, have a
Yamaha dealer blee d the system be-
fore operatin g the vehicle. Air in the
hy draulic system will diminish the
b rakin g performance, which may re-
sult in loss of control an d an acci-
d ent.

Brake li ght switches
The brake light should come on just
before braking takes effect. The brake
light is activated by switches connect-
ed to the brake lever and brake pedal.
Since the brake light switches are
components of the anti-lock brake sys-
tem, they should only be serviced by a
Yamaha dealer.

Checkin g the front an d rear
b rake pa ds
The front and rear brake pads must be
checked for wear at the intervals spec-
ified in the periodic maintenance and
lubrication chart.
EAU43432Front brake pad s
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
indicator groove has almost disap-
peared, have a Yamaha dealer replace
the brake pads as a set.

EAU22501Rear brake pad s
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.EAU40593
Checkin g the brake an d
YCC-S clutch flui d levels
Before riding, check that the brake and
YCC-S clutch fluids are above the mi-
nimum level marks. Check the brake
and YCC-S clutch fluid levels with the
tops of the reservoirs level. Replenish
the brake and YCC-S clutch fluids if
necessary.

YCC-S clutch
TIP

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 page
6-7.)
WARNING
EWA16021
Improper maintenance can result in
loss of brakin g a bility or YCC-S
clutch operation. O bserve these
precautions:  Insufficient brake or YCC-S
clutch flui d may allow air to en-
ter the b rake or YCC-S clutch
system, re ducin g brakin g or
YCC-S clutch performance.
 Clean the filler caps before re-
moving . Use only DOT 4 brake
flui d from a seale d container.
 Use only the specified b rake flu-
i d ; otherwise, the ru bber seals
may deteriorate, causin g leak-
a g e. 
Refill with the same type of
brake flui d. A ddin g a brake flui d
other than DOT 4 may result in a
harmful chemical reaction.
 Be careful that water or dust
d oes not enter the brake or
YCC-S clutch flui d reservoir
when refillin g. Water will si gnifi-
cantly lower the b oiling point of
the flui d an d ma y result in vapor
lock,

an d d irt may clo g the ABS
hy draulic unit valves.
NOTICE
ECA17641
Brake flui d may d amage painte d
surfaces or plastic parts. Always
clean up spille d flui d imme diately.
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.

Chan gin g the brake an d
YCC-S clutch fluid s
Have a Yamaha dealer change the
brake and YCC-S clutch fluids at the
intervals specified in the periodic main-
tenance and lubrication chart. In addi-
tion, have the oil seals of the brake and
YCC-S clutch master cylinders and
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:
Replace every four years.

bles and cable ends should be lubri-
cated if necessary. If a cable is
damaged or does not move smoothly,
have a Yamaha dealer check or re-
place it. WARNING! Dama ge to the
outer housin g of cab les may result
in internal rustin g an d cause inter-
ference with cab le movement. Re-
place damag ed cab les as soon as

Checkin g an d lu bricatin g the
throttle grip an d cab le
The operation of the throttle grip
should be checked before each ride. In
addition, the cable should be lubricat-
ed by a Yamaha dealer at the intervals
specified in the periodic maintenance
chart.
The throttle cable is equipped with a
rubber cover. Make sure that the cover
is securely installed. Even though the
cover is installed correctly, it does not
completely protect the cable from wa-
ter entry. Therefore, use care not to
pour water directly onto the cover or
cable when washing the vehicle. If the
cable or cover becomes dirty, wipe
clean with a moist cloth.
