Release the brake pedal slowly and wait several
seconds after it reaches the end of its travel.
Repeat above procedure until sufficient amount
of the fluid flows out of the bleed valve.
Perform step 1 at each bleed valve in the sequence
as follows:
2. Right front caliper lower side bleed valve
3. Rear caliper lower side bleed valve
4. Anti-dive plunger bleed valve
5. Rear caliper upper side bleed valve
Next, perform the air bleeding.
AIR BLEEDING
• Note that you may feel strong resistance on the
brake pedal during pumping to bleed air from the
right front caliper. This symptom is caused by
the delay valve function. Be sure to depress the
brake pedal fully to the bottom.
Air bleeding procedure must be performed in the
same way as in the fluid feeding procedure without
using a brake bleeder tool (page 15-11).
Repeat this procedure until air bubbles do not
appear in the plastic hose of each bleed valve.
After air bubbles cease to appear in the fluid, repeat
air bleeding procedure about 2 – 3 times.
Make sure that the bleed valves are closed and
operate the brake pedal. If it still feels spongy, bleed
the system again.
