Rear brake shoes
The rear brake is provided with a wear
indicator, which allows you to check the
brake shoe wear without having to
disassemble 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 dea-
ler replace the brake shoes as a set.

Checking the brake fluid levelInsufficient brake fluid may allow air to
enter the brake system, possibly causing
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
level is low, be sure to check the brake
pads for wear and the brake system for
leakage.Observe these precautions:
•
When checking the fluid level,
make sure that the top of the
master cylinder is level by turning
the handlebars.
•
Use only the recommended quality
brake fluid, otherwise the rubber
seals may deteriorate, causing
leakage and poor braking perfor-
mance.
Recommended brake fluid:
DOT 4
NOTE :
If DOT 4 is not available, DOT 3 can beused.•
Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and lead
to poor braking performance.
•
Be careful that water does not en-
ter the master cylinder when
refilling. Water will significantly
lower the boiling point of the fluid
and may result in vapor lock.

Changing the brake fluidHave a Yamaha dealer change the
brake fluid at the intervals specified in
the periodic maintenance and
lubrication chart. In addition, have the
brake hose replaced every four years
or whenever it is damaged or leaking.
EAU02962
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
lubricated if necessary. If a cable is
damaged or does not move smoothly,
have a Yamaha dealer check or replace
it.
Recommended lubricant:
Engine oil
EW000112
Damage to the outer sheath may
interfere with proper cable operation
and will cause the inner cable to
rust. Replace a damaged cable as
soon as possible to prevent unsafeconditions.

•
Brake fluid may deteriorate painted
surfaces or plastic parts. Always
clean up spilled fluid immediately.
•
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
suddenly, have a Yamaha dealer
check the cause.

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
EW000115
Securely support the scooter so thatthere 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 scooter on a level sur-
face and hold it in an upright po-
sition.
2. While applying the front brake,
push down hard on the
handlebars several times to check
if the front fork compresses and
rebounds smoothly.

If any damage is found or the front
fork does not operate smoothly,
have a Yamaha dealer check orrepair it.ZAUM0528

Checking the steeringWorn or loose steering bearings may
cause danger. Therefore, the operation
of the steering must be checked as
follows 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.
