the system.
TORQUE: 5.4 N·m (0.6 kgf·m, 4.0 lbf·ft)
After bleeding air, operate the left brake lever. If it
still feels spongy, bleed the system again.
Fill the reservoir with DOT 4 brake fluid to the upper
level.
If the brake bleeder is not available, perform the fol-
lowing procedure:
Tighten the front brake caliper lower bleed valve
and rear brake caliper bleed valve.
Fill the reservoir with DOT 4 brake fluid to the upper
level.
Operate the left brake lever several times to bleed
air from the master cylinder.
Connect a bleed hose to the rear brake caliper bleed
valve and bleed the system as follows:
1. Pump the left brake lever several (5 – 10) times,
then squeeze the left brake lever all the way and
loosen the bleed valve 1/4 of a turn. Wait several
seconds and then close the bleed valve.
• Do not release the brake lever until the bleed
valve has been closed.
2. Release the left brake lever slowly until the breed
valve has been closed.
3. Repeat the steps 1 and 2 until there are no air
bubbles in the bleed hose.
It is not a problem if the fluid flowing out from the
bleed valve contains air bubbles because the lines
will be bled in later steps.
