PERIODIC MAINTENANCE AND MINOR REPAIR
Observe these precautions:
8
When checking the fluid level,
make sure that the top of the
master cylinder or brake fluid
reservoir is level.
8
Use only the recommended qual-
ity brake fluid, otherwise the rub-
ber seals may deteriorate, caus-
ing leakage and poor braking
performance.

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.
8
Oil seals: Replace every two
years.
8
Brake hoses: Replace every four
years.
8
Refill with the same type of brake
fluid. Mixing fluids may result in a
harmful chemical reaction and
lead to poor braking perfor-
mance.
8
Be careful that water does not
enter the master cylinder when
refilling. Water will significantly
lower the boiling point of the fluid
and may result in vapor lock.
8
Brake fluid may deteriorate paint-
ed surfaces or plastic parts.
Always clean up spilled fluid
immediately.
8
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.
