  1. On level ground, jack up the vehicle and support it evenly on safety stands.
  2. Remove the bleeder cap and attach a vinyl tube to the bleeder screw. See Fig 1.
  3. Place the other end of the vinyl tube in a clear container.
  4. The first person depresses the brake pedal a few times, and then holds it in the depressed position.
  5. The second person loosens the bleeder screw, drains out the fluid and closes the bleeder screw.
  6. Repeat steps 4 and 5 until no air bubbles are seen. The reservoir should be kept about 3/4 full during bleeding to prevent air from reentering the lines.
  7. Inspect for correct brake operation.
  8. Verify that there is no fluid leakage. Wipe off any spilled fluid immediately.
  9. After bleeding the brakes, add brake fluid to the maximum level.
