Checking the brake lever free
play There should be no free play at the
brake lever end. If there is free play,
have a Yamaha dealer inspect the
brake system.
WARNING
EWA14211
A soft or spongy feeling in the brake
lever can indicate the presence of air
in the hydraulic system. If there is air
in the hydraulic system, have a
Yamaha dealer bleed the system be- fore operating the vehicle. Air in the
hydraulic system will diminish the braking performance, which may re-
sult in loss of control and an acci-
dent.

Checking the front and rear
brake pads The front and rear brake pads must be
checked for wear at the intervals spec-
ified in the periodic maintenance and
lubrication chart.
EAU22420
Front brake pads
Each front brake pad is provided with a
wear indicator groove, which allows
you to check the brake pad wear with-
out having to disassemble the brake.
To check the brake pad wear, check
the wear indicator groove. If a brake
pad has worn to the point that the wearindicator groove has almost disap-
peared, have a Yamaha dealer replace
the brake pads as a set.
EAU46291
Rear brake pads
Each rear brake pad is provided with
wear indicator grooves, which allow
you to check the brake pad wear with-
out having to disassemble the brake.
To check the brake pad wear, check
the wear indicator grooves. If a brake
pad has worn to the point that a wear
indicator groove almost appears, have
a Yamaha dealer replace the brake
pads as a set.

Checking the brake fluid level Before riding, check that the brake fluid
is above the minimum level mark.
Check the brake fluid level with the top
of the reservoir level. Replenish the
brake fluid if necessary.
Front brakeRear brake
TIPThe rear brake fluid reservoir is located
behind panel A. (See page 6-8.)
WARNING
EWA15990
Improper maintenance can result in
loss of braking ability. Observe
these precautions:●
Insufficient brake fluid may al-
low air to enter the brake sys-
tem, reducing braking
performance.
●
Clean the filler cap before re-
moving. Use only DOT 4 brake
fluid from a sealed container.
●
Use only the specified brake flu-
id; otherwise, the rubber seals
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
lock.
NOTICE
ECA17640
Brake fluid may damage painted sur-
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
down. A low brake fluid level may indi-
cate worn brake pads and/or brake sys-
tem 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.
EAU22731
Changing the brake fluid Have a Yamaha dealer change the

placed at the intervals listed below or
whenever they are damaged or leak-
ing.●
Oil seals: Replace every two
years.
●
Brake hoses: Replace every four
years.
