AIR BLEEDING THE BRAKE FLUID CIRCUIT
Air trapped in the brake fluid circuit acts like a cushion absorb a
large proportion of the pressure developed by the master cylin-
der 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 installing the brake and restoring
the brake system to the normal condition, the brake fluid circuit
be purged of air in the following manner:
• Fill the front or rear brake reservoir with the specified brake
fluid to the top of the inspection window or the upper limit line.
Replace the reservoir cap to prevent dirt from entering.
• Attach a hose to the air bleeder valve, and insert the free end
of the hose into a receptacle.
• Squeeze and release the brake lever several times in rapid
succession and squeeze the lever fully without releasing it.
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 handle-
bar grip reaching bottom of the stroke. Then, close the air
bleeder valve, pump and squeeze the lever and open the
valve. 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.
• Close the air bleeder valve, and disconnect the hose. Fill the
reservoir with brake fluid to the top of the inspection window
or the upper limit line.
