Each front 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 the wear
indicator grooves have almost disap-
peared, have a Yamaha dealer replace
the brake pads as a set.

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

WARNING
EWA15991
Improper maintenance can result in
loss of b raking a bility. O bserve
these precautions: Insufficient brake flui d may al-
low air to enter the brake sys-
tem, re ducin g brakin g
performance.
Clean the filler cap before re-
movin g. Use only DOT 4 brake
flui d from a seale d container.
Use only the specified b rake flu-
i d ; otherwise, the ru bber seals
may deteriorate, causin g leak-
a g e.
Refill with the same type of
brake flui d. A dding a brake fluid
other than DOT 4 may result in a
harmful chemical reaction.
Be careful that water d oes not
enter the brake flui d reservoir
when refillin g. Water will sig nifi-
cantly lower the boilin g point of
the flui d an d may result in vapor
lock.
NOTICE
ECA17641
Brake flui d may d amage painte d
surfaces or plastic parts. Always
clean up spilled fluid imme diately.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
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.

Drive belt slackThe drive belt slack should be checked
and adjusted at the intervals specified
in the periodic maintenance and lubri-

To check the d rive belt slack
1. Place the vehicle on the side- stand.
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 measure-
ment noted in step 3.
