Checkin g the front an d rear
b rake pa ds
The front and rear brake pads must be
checked for wear at the intervals spec-
ified in the periodic maintenance and
lubrication chart.
EAU22411Front brake pa ds
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.
EAU46292Rear 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.

Checkin g the brake flui d 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.

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 brake sys-
tem, re ducing 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 specifie d 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 d oes not
enter the brake flui d reservoir
when refillin g. Water will si gnifi-
cantly lower the b oiling 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 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.

7 To install the front wheel
1. Lift the wheel up between the fork legs.
TIP
Make 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 on the ground, install the remov-
able sidestand, and then rest the
motorcycle on it.
4. Install the washer and axle nut, and then tighten the axle nut to the
specified torque.

To remove the rear wheel
WARNING
EWA10822
To avoi d injury, securely support the
vehicle so there is no dan ger of it
fallin g over.
1. Loosen the axle nut.
2. Lift the rear wheel off the ground.
(See page 7-28.)
3. Loosen the locknut, and then loosen the drive chain slack ad-
justing bolt on each side of the
swingarm.
4. Remove the axle nut and washer.
5. Push the wheel forward, and then remove the drive chain from the

TIP
 If the drive chain is difficult to re-
move, remove the wheel axle first,
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.
TIP
A rubber mallet may be useful to
tap the wheel axle out.
 The drive chain pullers may fall out
when removing the wheel axle.
7. Remove the wheel. NOTICE: Do
not apply the brake after the
wheel an d b rake disc have been
remove d, otherwise the brake
pa ds will b e forced shut.
[ECA11073]
To install the rear wheel
1. Insert the rear wheel between the swingarm and then install the
drive chain onto the rear sprocket. 2. Install the brake caliper and drive
chain pullers, and then install the
wheel by inserting the wheel axle
from the right 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.
4. Lower the rear wheel so that it is
on the ground, install the remov-
able sidestand, and then rest the
motorcycle on it.
5. Adjust the drive chain slack. (See page 7-21.)
6. Tighten the locknuts and the axle nut to their specified torques.
