NOTE:
The bleeding order of the hydraulic brake sys-
tem is the following:
1. Front brake calipers
2. Brake equalizer
3. Rear brake caliper
d. Place the other end of the hose into a con-
tainer.
e. Slowly apply the brake lever or brake pedal
several times.
f. Fully squeeze the brake lever or fully
depress the brake pedal and hold it in posi-
tion.
g. Loosen the bleed screw.
NOTE:

Loosening the bleed screw will release the
pressure 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.
NOTE:
If the air is not completely bled from the
hydraulic system after bleeding the rear brake
caliper, repeat the bleeding procedure for the
brake equalizer and the rear brake caliper.
j. Tighten the bleed screw to specification.
