BRAKE AIR BLEEDING
Any air which may have been trapped in the brake fluid
circuit must be bled completely.
If the brake lever or brake pedal feels spongy or weak,
then most likely there is air in the hydraulic circuit.
To bleed the air from the front brake, use the following
procedure.
1. Connect a clear hose to the air bleeder valve and
run the hose into a suitable clear container.
2. Pour approximately 1/2 in of brake fluid into the con-
tainer so that the end of the clear hose is sub-
merged and cannot draw any additional air back into
the circuit during the air bleeding servicing.
3. Close the valve, pump and squeeze the lever, and
open the valve while squeezing brake lever.
4. Repeat this process until the fluid flowing into the
receptacle no longer contains air bubbles.
NOTE:
Do not drop brake fluid level below lower level
line while bleeding air.
5. After bleeding the brake circuit, tighten the bleeder
valve to the specified torque.
Replace the rubber protective cap.
6. Be sure to check the brake fluid level in the reser-
voir.
