Checking the front an d rear
b rake pa dsThe front and rear brake pads must be
checked for wear at the intervals spec-
ified in the periodic maintenance and
lubrication chart.
EAU22411
Front brake pad s
Each front brake pad is provided with a
wear indicator, which allows you to
check the brake pad wear without hav-
ing to disassemble the brake. To check
the brake pad wear, check the position
of the wear indicator while applying the
brake. If a brake pad has worn to the
point that the wear indicator almost touches the brake disc, have a
Yamaha dealer replace the brake pads
as a set.
EAU46292
Rear
brake pa ds
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.
EAU22582
Checkin g the brake flui d levelBefore 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.

WARNING
EWA15991
Improper maintenance can result in
loss of brakin g a bility. O bserve
these precautions:  Insufficient brake flui d may al-
low air to enter the b rake sys-
tem, re ducin g brakin g
performance.
 Clean the filler cap before re-
moving . Use only DOT 4 b rake
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 ddin g a brake flui d
other than DOT 4 may result in a
harmful chemical reaction.
 Be careful that water does not
enter the brake flui d reservoir
when refillin g. Water will si gnifi-
cantly lower the boilin g point of
the flui d an d may result in vapor
lock.
NOTICE
ECA17641
Brake flui d may damag e painted
surfaces or plastic parts. Always
clean up spille d flui d 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.

To install the front wheel
1. Lift the wheel up between the fork legs.TIPMake sure that there is enough space
between the brake pads before install-
ing the wheel.2. Insert the wheel axle from the rightside. 3. Lower the front wheel so that it is

and then lift the wheel upward
enough to remove the drive chain
from the rear sprocket.
 The drive chain does not need to
be disassembled in order to re-
move and install the rear wheel.
6. While supporting the brake caliper
and slightly lifting the wheel, pull
the wheel axle out.TIPA rubber mallet may be useful to tap
the wheel axle out.7. Remove the wheel. NOTICE: Do
not apply the b rake after the
wheel an d b rake disc have been

To install the rear wheel
1. Install the drive chain onto the rear sprocket. 2. Install the wheel and the brake cal-
iper bracket by inserting the wheel
axle from the right-hand side.
TIPMake sure that the slot in the
brake caliper bracket is fit over the
retainer on the swingarm.
 Make sure that there is enough
space between the brake pads
before installing the wheel.3. Install the washer and axle nut.
