BrakesReplacement of brake components requires
professional knowledge. Brake service should
be performed by a Yamaha dealer.
WARNING
Operating with improperly serviced or ad-
justed brakes could lead to a loss in brak-
ing ability and an accident.5B410019Checking the front and rear brake padsEach brake pad is provided with wear indica-
tor grooves, which allow you to check the
brake pad wear without having to disassem-
ble the brake. To check the brake pad wear,
check the wear indicator grooves. If a brake
pad has worn to the point that the wear indica-
tor grooves have almost disappeared, have a
Yamaha dealer replace the brake pads as a
set. The wheels need to be removed to check the
brake pads. (See pages 8-39, 8-41 for wheel
removal and installation procedures.)

WARNING
Improper maintenance can result in loss of
braking ability. Observe these precau-
tions:●
Insufficient brake fluid may allow air
to enter the brake system, reducing
braking performance.
●
Clean the filler cap before removing.
Use only DOT 4 brake fluid from a
sealed container.
●
Use only the specified brake fluid;
otherwise, the rubber seals may dete-
riorate, causing leakage.
●
Refill with the same type of brake flu-
id. Adding a brake fluid other than
DOT 4 may result in a harmful chemi-
cal reaction.
●
Be careful that water does not enter
the brake fluid reservoir when refill-
ing. Water will significantly lower the
boiling point of the fluid and may re-
sult in vapor lock.
NOTICEBrake fluid may damage painted surfaces
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 down. A low
brake fluid level may indicate worn brake
pads and/or brake system leakage; therefore,
be sure to check the brake pads for wear and
the brake system for leakage. If the brake fluid
level goes down suddenly, have a Yamaha
dealer check the cause before further riding.EVU00860Brake fluid replacementComplete fluid replacement should be done
only by trained Yamaha service personnel.
Have a Yamaha dealer replace the following
components during periodic maintenance or
when they are damaged or leaking.●
Replace the oil seals every two years.
●
Replace the brake hoses every four years.
