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.
EAU43431
Front brake pads
The front brake calipers are equipped
with two sets of 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 a brake pad for wear, check
its wear indicator groove. If a brake pad
has worn to the point that the wear indi- cator groove has almost disappeared,
have a Yamaha dealer replace the
brake pads as a set.
EAU22500
Rear brake pads
Check each rear brake pad for damage
and measure the lining thickness. If a
brake pad is damaged or if the lining
thickness is less than 0.8 mm (0.03 in),
have a Yamaha dealer replace the
brake pads as a set.
EAU38631
Checking the bra
ke and clutch
fluid levels Before riding, check that the brake and
clutch fluids are above the minimum
level marks. Check the brake and
clutch fluid levels with the tops of the
reservoirs level. Replenish the brake
and clutch fluids if necessary.

TIPThe rear brake fluid reservoir is located
under the rider seat. (See page 3-16.)
WARNING
EWA16000
Improper maintenance can result in
loss of braking ability or clutch oper-
ation. Observe these precautions:●
Insufficient brake or clutch fluid
may allow air to enter the brake
or clutch system, reducing
braking or clutch performance.
●
Clean the filler caps 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 or clutch fluid
reservoir when refilling. Water will significantly lower the boil-
ing point of the fluid and may re-
sult 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. A low clutch
fluid level may indicate clutch system
leakage; therefore, be sure to check the
clutch system for leakage. If the brake
or clutch fluid level goes down sudden-
ly, have a Yamaha dealer check the
cause before further riding.

EAU22751
Changing the brake and
clutch fluids Have a Yamaha dealer change the
brake and clutch fluids at the intervals
specified in the TIP after the periodic
maintenance and lubrication chart. In
addition, have the oil seals of the brake
and clutch master cylinders and cali-
pers as well as the brake and clutch
hoses replaced at the intervals listed
below or whenever they are damaged
or leaking.●
Oil seals: Replace every two
years.
●
Brake and clutch hoses: Replace
every four years.
EAU23040
Drive belt slack The drive belt slack should be checked
and adjusted at the intervals specified
in the periodic maintenance and lubri-
cation chart.
EAU38410
To check the drive belt slack1. Place the vehicle on the sidestand.
2. Note the current position of the drive belt using the marks near the
drive belt check hole.TIPThe marks near the drive belt check
hole are 5.0 mm (0.2 in) apart.
3. Note the position of the drive beltwith a force of 45 N (4.5 kgf, 10 lbf)
applied to the belt with a belt ten-
sion gauge as shown.TIPA belt tension gauge is available at a
Yamaha dealer.4. Calculate the drive belt slack by subtracting the measurement not-
ed in step 2 from the measurement
noted in step 3.
