H. CHECKING THE BRAKE FLUID
LEVEL
1. Stand the machine on a level surface.
NOTE:
Make sure that the machine is upright.
2. Check:
D
brake fluid level
Below the minimum level mark
(a)
>
Add the recommended brake
fluid to the proper level.
Recommended brake fluid:
DOT 4
(A) Front brake
(B) Rear brake
W
D
Use only designated brake fluid.
Other brake fluids may cause the
rubber seals to deteriorate, causing
leakage and poor brake perfor-
mance.
D
Refill with the same type of brake
fluid that is already in the system.
Mixing brake fluids may result in a
harmful chemical reaction, leading
to poor brake performance.
D D
When refilling, be careful that water
does not enter the reservoir. Water
will significantly lower the boiling
point of the brake fluid and could
cause vapor lock.
CAUTION:
Brake fluid may damage painted sur-
faces and plastic parts. Therefore,
always clean up any split brake fluid
immediately.
NOTE:
In order to ensure a correct reading of the
brake fluid level, make sure that the top of
the reservoir is level.

I. ADJUSTING THE REAR BRAKE
1. Measure:
D
brake pedal position
(distance (a) from the top of the rider
footrest to the top of the brake pedal)
Out of specification
>
Adjust.
Brake pedal position
(above the top of the rider footrest):
5 mm (0.20 in)
2. Adjust:
D
brake pedal position
a. Loosen the locknut (1).
b. Turn the adjusting nut (2) in direction
(a) or (b) until the specified brake pedal
position is obtained.
Direction (a):
Brake pedal is raised.
Direction (b):
Brake pedal is lowered.
W
D D
Adjust the pedal position between
the highest position (A) and the low-
est position (B) as shown. (In this
adjustment, the bolt (3) end (c)
should protrude out of the 2 mm
(0.08 in) (d) away from the brake
pedal (5)).
D D
After the pedal position adjustment,
make sure that the rear brake does
not drag.
c. Tighten the locknut (1).
W
A soft or spongy feeling in the brake
pedal can indicate the presence of air
in the brake system. Before the vehicle
is operated, the air must be removed
by bleeding the brake system. Air in
the brake system will considerably
reduce braking performance and could
result in loss of control and possibly
an accident. Therefore, check the brake
system and bleed if necessary.
CAUTION:
After adjusting the brake pedal posi-
tion, make sure that there is no brake
drag.
