4A-5 Brake Control System and Diagnosis:

Air Bleeding from Front Brake Fluid Circuit

B931H24106009

Air trapped in the brake fluid circuit acts like a cushion to
absorb a large proportion of the pressure developed by
the master cylinder and thus interferes with the full
braking performance of the brake caliper. The presence
of air is indicated by “sponginess” of the brake lever and
also by lack of braking force. Considering the danger to
which such trapped air exposes the machine and rider, it
is essential that after remounting the brake and restoring
the brake system to the normal condition, the brake fluid
circuit be purged of air in the following manner:

CAUTION

!

• Make sure that the vehicle is supported

securely.

• Handle brake fluid with care: the fluid

reacts chemically with paint, plastic,
rubber materials, etc.

1) Fill the master cylinder reservoir to the top of the

inspection window. Place the reservoir cap to
prevent dirt from entering.

2) Attach a hose to the air bleeder valve, and insert the

free end of the hose into a receptacle.

3) Squeeze and release the brake lever several times

in rapid succession and squeeze the lever fully
without releasing it.

4) Loosen the air bleeder valve by turning it a quarter of

a turn so that the brake fluid runs into the receptacle,
this will remove the tension of the brake lever
causing it to touch the handlebar grip.

5) Close the air bleeder valve, pump and squeeze the

lever, and open the valve.

6) Repeat this process until the fluid flowing into the

receptacle no longer contains air bubbles.

NOTE

While bleeding the brake system, replenish
the brake fluid in the reservoir as necessary.
Make sure that there is always some fluid
visible in the reservoir.

7) Close the air bleeder valve and disconnect the hose.

Tightening torque
Front brake air bleeder valve (a): 6 N·m (0.6 kgf-
m, 4.5 lbf-ft)

8) Fill the reservoir with brake fluid to the upper mark of

the reservoir.

9) Install the reservoir cap.
