Periodic maintenance and adjustment
may deteriorate, causing leak-

age.
Refill with the same type of

brake fluid. Adding a brake fluid
other than DOT 4 may result in a
harmful chemical reaction.

Be 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

NOTICE
Brake fluid may damage painted sur-
7
faces or plastic parts. Always clean
up spilled fluid immediately.

As the brake pads wear, it is normal for
the brake fluid level to gradually go
9
down. A low brake fluid level may indi-
cate worn brake pads and/or brake sys-
10
tem leakage; therefore, be sure to
check the brake pads for wear and the
brake system for leakage. If the brake
11
fluid level goes down suddenly, have a
Yamaha dealer check the cause before
12
further riding.
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 cylinders and calipers as
well as the brake hoses replaced at the
intervals listed below or whenever they
are damaged or leaking.
Oil seals: Replace every two
years.
Brake hoses: Replace every four
