J. CHECKING THE BRAKE FLUID
LEVEL
1. Stand the vehicle on a level surface.
NOTE:
_
Place the vehicle on a suitable stand.
●
Make sure that the vehicle is upright.
●
2. Check:
brake fluid level
●
Below the minimum level mark (a) →
Add the recommended brake fluid to
the proper level.
Recommended brake fluid
DOT 4
WARNING
_
Use only designated brake fluid.
●
Other brake fluids may cause the
rubber seals to deteriorate, causing
leakage and poor brake perfor-
mance.

K. BLEEDING THE HYDRAULIC
BRAKE SYSTEM
WARNING
_
Bleed the hydraulic brake system
whenever:
the system was disassembled,
●
a brake hose was loosened or
●
removed,
the brake fluid level is very low,
●
brake operation is faulty.
●
NOTE:
_
Be careful not to spill any brake fluid or
●
allow the brake master cylinder reser-
voir to overflow.
When bleeding the hydraulic brake sys-
●
tem, make sure that there is always
enough brake fluid before applying the
brake. Ignoring this precaution could
allow air to enter the hydraulic brake
system, considerably lengthening the
bleeding procedure.
If bleeding is difficult, it may be neces-
●
sary to let the brake fluid settle for a
few hours. Repeat the bleeding proce-
dure when the tiny bubbles in the hose
have disappeared.
–19–
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.
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.
1. Bleed:
hydraulic brake system
●
a. Add the recommended brake fluid to
the proper level.
b. Install the brake master cylinder reser-
voir diaphragm.
c. Connect a clear plastic hose (1) tightly
to the bleed screw (2).
d. Place the other end of the hose into a
container.
e. Slowly squeeze the brake lever several
times and release it.
f. Fully squeeze the brake lever and do
not release it.
g. Loosen the bleed screw. This will
release the tension and cause the
brake lever to contact the throttle grip.
h. Tighten the bleed screw and then
release the brake lever.
i. Repeat steps (e) to (h) until all of the air
bubbles have disappeared from the
brake fluid in the plastic hose.
j. Tighten the bleed screw to specifica-
tion.
Bleed screw
6 Nm (0.6 m · kg, 4.3 ft · lb)
k. Fill the reservoir to the proper level.
Refer to "CHECKING THE BRAKE
FLUID LEVEL".
WARNING
_
After bleeding the hydraulic brake sys-
tem, check the brake operation.
