BLEEDING THE HYDRAULIC BRAKE SYSTEM
INSP
ADJ
NOTE:
1. Remove:
Reservoir cap
Reservoir diaphragm
Be careful not to spill any brake fluid or allow
the brake master cylinder reservoir to over-
flow.
When bleeding the hydraulic brake system,
make sure that there is always enough brake
fluid before applying the brake. Ignoring this
precaution could allow air to enter the hydrau-
lic brake system, considerably lengthening the
bleeding procedure.
If bleeding is difficult, it may be necessary to let
the brake fluid settle for a few hours.
Repeat the bleeding procedure when the tiny
bubbles in the hose have disappeared.
2. Bleed:
hydraulic brake system
a.
Add the recommended brake fluid to the
proper level.
b.
Install the brake master cylinder reservoir
diaphragm.
c.
Connect a clear plastic hose
1
tightly to the
bleed screw

.
d.
Place the other end of the hose into a con-
tainer.
e.
Slowly squeeze the brake lever several
times.
f.
Fully squeeze the brake lever without re-
leasing 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 specification.
