BLEEDING THE HYDRAULIC BRAKE
SYSTEM (ABS)
WARNING
EWA14000
Always bleed the brake system when the
brake related parts are removed.
NOTICE
ECA22640
• Bleed the brake system in the following or-
der.
• 1st step: Front brake master cylinder
• 2nd step: Front brake calipers
• 3rd step: Rear brake caliper
WARNING
EWA16530
Bleed the ABS whenever:
• the system is disassembled.
• a brake hose is loosened, disconnected or
replaced.
• the brake fluid level is very low.
• brake operation is faulty.
TIP
• Be careful not to spill any brake fluid or allow
the brake fluid reservoir to overflow.
• When bleeding the ABS, make sure that there
is always enough brake fluid before applying
the brake. Ignoring this precaution could allow
air to enter the ABS, 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.
1. Bleed:
• ABS
a. Fill the brake fluid reservoir to the proper
level with the specified brake fluid.
b. Install the diaphragm (brake fluid reser-
voir).
c. Connect a clear plastic hose “1” tightly to
the bleed screw “2”.
d. Place the other end of the hose into a con-
tainer.
e. Slowly apply the brake several times.
f. Fully squeeze the brake lever or fully de-
press the brake pedal and hold it in posi-
tion.
g. Loosen the bleed screw.
TIP
Loosening the bleed screw will release the pres-
sure and cause the brake lever to contact the
throttle grip or the brake pedal to fully extend.
h. Tighten the bleed screw and then release
the brake lever or brake pedal.
i. Repeat steps (e) to (h) until all of the air
bubbles have disappeared from the brake
fluid in the plastic hose.
j. Check the operation of the hydraulic unit.
Refer to “HYDRAULIC UNIT OPERA-
TION TEST” on page 4-79.
NOTICE
ECA17061
Make sure that the main switch is turned to
“OFF” before checking the operation of the
hydraulic unit.
k. After operating the ABS, repeat steps (e)
to (i), and then fill the brake fluid reservoir
to the proper level with the specified brake
fluid.
