ZAUM00591. Wear indicator
2. Wear limit lineThe rear brake is provided with a wear
indicator, which allows you to check the
brake shoe wear without having to dis-
assemble the brake. To check the brake
shoe wear, check the position of the
wear indicator while applying the brake.
If a brake shoe has worn to the point
that the wear indicator reaches the wear
limit line, have a Yamaha dealer replace
the brake shoes as a set. groove has almost disappeared, have a
Yamaha dealer replace the brake pads
as a set.

Checking the brake fluid levelZAUM00**

1. MInimum level markInsufficient brake fluid may allow air to
enter the brake system, possibly caus-
ing it 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 sys-
tem for leakage.
Observe these precautions:8When checking the fluid level, make
sure that the top of the master cyl-
inder is level by turning the handle-
bars.
8Use only the recommended quality
brake fluid, otherwise the rubber
seals may deteriorate, causing
leakage and poor braking perfor-
mance.
Recommended brake fluid:
DOT 4
8Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and lead
to poor braking performance.
8Be careful that water does not en-
ter the master cylinder when refill-
ing. Water will significantly lower the
boiling point of the fluid and may
result in vapor lock.
8Brake fluid may deteriorate painted
surfaces or plastic parts. Always
clean up spilled fluid immediately.

PERIODIC MAINTENANCE AND MINOR REPAIR8As 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.
EAU22720
Changing the brake fluidHave a Yamaha dealer change the brake
fluid at the intervals specified in the
NOTE after the periodic maintenance
and lubrication chart. In addition, have
the oil seals of the brake master cylin-
der and caliper as well as the brake hose
replaced at the intervals listed below or
whenever they are damaged or leaking.
8Oil seals: Replace every two years.
8Brake hose: Replace every four
years.
EAU23100
Checking and lubricating the
cablesThe operation of all control cables and
the condition of the cables should be
checked before each ride, and the
cables and cable ends should be lubri-
cated if necessary. If a cable is dam-
aged or does not move smoothly, have
a Yamaha dealer check or replace it.
Recommended lubricant:
Engine oil
EWA10720
wDamage 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 condi-
tions.

Checking the front forkThe condition and operation of the front
fork must be checked as follows at the
intervals specified in the periodic main-
tenance and lubrication chart.
To check the condition
EWA10750
wSecurely support the motorcycle so
that there is no danger of it falling
over.Check the inner tubes for scratches,
damage and excessive oil leakage.
To check the operation
1. Place the motorcycle on a level sur-
face and hold it in an upright posi-
tion.
2. While applying the front brake, push
down hard on the handlebars sev-
eral times to check if the front fork
compresses and rebounds
smoothly.

Checking the steeringWorn or loose steering bearings may
cause danger. Therefore, the operation
of the steering must be checked as fol-
lows at the intervals specified in the
periodic maintenance and lubrication
chart.
1. Place a stand under the engine to
raise the front wheel off the ground.
EWA10750
wSecurely support the motorcycle so

legs and try to move them forward
and backward. If any free play can
be felt, have a Yamaha dealer check
or repair the steering.
