Manual Bleeding


Manual bleeding requires two people and a degree of patience and cooperation.

  1. Follow the preparatory steps, above.
  3. Attach a length of rubber hose over the bleeder screw and place the other end of the hose in a glass jar, submerged in brake fluid.
  5. Have your assistant press down on the brake pedal, then open the bleeder screw 1 / 2 - 3 / 4 turn.
  7. The brake pedal will go to the floor.
  9. Close the bleeder screw-preferably before the pedal reaches the floor. Tell your assistant to allow the brake pedal to return slowly.
  11. Repeat these steps to purge all air from the system.
  13. When bubbles cease to appear at the end of the bleeder hose, close the bleeder screw and remove the hose. Check that the pedal is firm or at least more firm than it was when you started. If not, continue the procedure.
  15. Check the master cylinder fluid level and add fluid accordingly. Do this after bleeding each wheel.
  17. Repeat the bleeding operation at the remaining three wheels, ending with the one closet to the master cylinder.
  19. Fill the master cylinder reservoir to the proper level.
    If there is excessive air in the system, it is possible that the stroke of the brake pedal will be insufficient to purge the lines. In this case a pressure bleeder or vacuum bleeder is the easiest solution.
