Vacuum Bleeding


Vacuum bleeding can be carried out by one person. Since a good vacuum bleeder will normally move more fluid than a brake pedal stroke, this procedure is preferred. These tools are inexpensive and readily available at auto parts outlets.

  1. Follow the preparatory steps, above.
  3. Attach the vacuum bleeder according to the manufacturer's recommendations.
  5. Pump up the unit until maximum vacuum is reached. Loosen the bleeder screw slightly until bubbles and fluid issue forth. Close the screw before the vacuum is equalized.
  7. Repeat the procedure until fluid without bubbles issues from the bleeder screw.
  9. Keep a close check on master cylinder fluid level during this procedure as vacuum bleeders move considerable amounts of fluid.
