PERIODIC MAINTENANCE AND MINOR REPAIR
Observe these precautions:
8When checking the fluid level,
make sure that the top of the
brake fluid reservoir is level.
8Use only the recommended qual-
ity brake fluid, otherwise the rub-
ber seals may deteriorate, caus-
ing leakage and poor braking
performance.
8Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking perfor-
mance.
8Be careful that water does not
enter the brake fluid reservoir
when refilling. Water will signifi-
cantly lower the boiling point of
the fluid and may result in vapor
lock. Recommended brake fluid:
DOT 4
8Brake fluid may deteriorate paint-
ed surfaces or plastic parts.
Always clean up spilled fluid
immediately.
8As 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.
EAU03238
Changing the brake fluidHave 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 brake master cylinder
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.

occurring, keep the drive chain
slack within the specified limits.3.Tighten both locknuts, and then
tighten the axle nut to the speci-
fied torque.
