Hydraulic brake and clutch systems
• After disassembling the brake or clutch master cylinders, caliper cylinders or clutch release cylinder, always change
the fluid. Regularly check the brake and clutch fluid levels and fill the reservoirs as required.
• Replace the oil seals on the inner parts of the brake or clutch master cylinders, caliper cylinders and clutch release
cylinder every two years.
• Replace the brake and clutch hoses every four years or if cracked or damaged.

6Tire inspection
The tires must be checked before each
ride. If the center tread depth reaches
the specified limit, if the tire has a nail
or glass fragments in it, or if the side-
wall is cracked, have a Yamaha dealer
replace the tire immediately.
CE-08ENOTE:_ The tire tread depth limits may differ
from country to country. Always comply
with the local regulations. _
EW000079
WARNING
_ l
Have a Yamaha dealer replace
excessively worn tires. Besides
being illegal, operating the
motorcycle with excessively
worn tires decreases riding sta-
bility and can lead to loss of
control.
l
The replacement of all wheel-
and brake-related parts, includ-
ing the tires, should be left to a
Yamaha dealer, who has the
necessary professional knowl-
edge and experience.

Cast wheels To maximize the performance, durabil-
ity, and safe operation of your motor-
cycle, note the following points
regarding the specified wheels.l
The wheel rims should be checked
for cracks, bends or warpage be-
fore each ride. If any damage is
found, have a Yamaha dealer re-
place the wheel. Do not attempt
even the smallest repair to the
wheel. A deformed or cracked
wheel must be replaced.
l
The wheel should be balanced
whenever either the tire or wheel
has been changed or replaced. An
unbalanced wheel can result in
poor performance, adverse han-
dling characteristics, and a short-
ened tire life.
l
Ride at moderate speeds after
changing a tire since the tire sur-
face must first be “broken in” for it
to develop its optimal characteris-
tics.
EAU00713
Adjusting the 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, adjust the brake light switch
as follows.
Turn the adjusting nut while holding the
rear brake light switch in place. To
make the brake light come on earlier,
turn the adjusting nut in direction
a. To
make the brake light come on later,
turn the adjusting nut in direction
b.
EAU00715
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. Each brake pad is
provided with a wear indicator, which
allows you to check the brake pad wear
without having to disassemble the
brake. To check the brake pad wear,
check the position of the wear indicator
while applying the brake. If a brake pad
has worn to the point that the wear indi-
cator almost touches the brake disc,
have a Yamaha dealer replace the
brake pads as a set.

Checking the brake fluid level Insufficient brake fluid may allow air to
enter the brake or clutch systems, pos-
sibly causing them to become ineffec-
tive.
Before riding, check that the brake fluid
is above the minimum level mark and
replenish if necessary. A low brake flu-
id level may indicate worn brake pads
and/or brake system leakage. If the
brake level is low, be sure to check the
brake pads for wear and the brake sys-
tem for leakage.Observe these precautions:
l
When checking the fluid level,
make sure that the top of the res-
ervoir is level.
l
Use only the recommended quali-
ty brake fluid, otherwise the rubber
seals may deteriorate, causing
leakage and poor braking or clutch
performance.

l
Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking or clutch per-
formance.
l
Be careful that water does not en-
ter the brake fluid reservoir when
refilling. Water will significantly
lower the boiling point of the fluid
and may result in vapor lock.
l
Brake fluid may deteriorate paint-
ed surfaces or plastic parts. Al-
ways clean up spilled fluid
immediately.
l
As the brake pads wear, it is nor-
mal for the brake fluid level to
gradually go down. However, if the
brake fluid level goes down sud-
denly, have a Yamaha dealer
check the cause.
l
Make sure to return the fluid reser-
voir diaphragm to the original
shape before installing it.

Changing the brake fluid Have a Yamaha dealer change the
brake fluid at the intervals specified in
the periodic maintenance and lubrica-
tion chart. In addition, have the oil seals
of the master cylinder and caliper as
well as the brake hoses replaced at the
intervals listed below or whenever they
are damaged or leaking.l
Oil seals: Replace every two
years.

Brake hoses: Replace every four
years.

Checking and lubricating the
cables The operation of all control cables and
the condition of the cables should be
checked before each ride, and the ca-
bles and cable ends should be lubricat-
ed if necessary. If a cable is damaged
or does not move smoothly, have a
Yamaha dealer check or replace it.

WARNING
_ Damage to the outer sheath may in-
terfere with proper cable operation
and will cause the inner cable to
rust. Replace a damaged cable as
soon as possible to prevent unsafe
conditions. _
