Bleeding the Brake System


  1. Raise the vehicle and safely support it.
  3. Remove both front and rear wheels.
  5. Draw out the brake fluid from master cylinder with syringe.
  7. Refill reservoir tank with recommended brake fluid.
  9. Install one end of a vinyl tube onto the air bleeder and insert the other end of the tube into a container to collect the brake fluid.
  11. Instruct your co-worker to depress the brake pedal slowly two or three times and then hold it depressed.
  13. Loosen bleeder screw approximately 1/4 turn until a small amount of brake fluid drains into container, and then quickly tighten screw.
  15. Repeat again from the two former procedures above until there are no air bubbles in drained brake fluid and new fluid flows through vinyl tube.
    Add brake fluid as necessary while performing the air bleed operation, in order to prevent the tank from running short of brake fluid.

  17. After completing the bleeding operation, hold brake pedal depressed and tighten screw and install bleeder cap.
  19. Bleed air from each wheel cylinder using the same procedures as described above.
  21. Depress brake pedal and hold it there for approximately 20 seconds. At this time check pedal to see if it shows any unusual movement. Visually inspect bleeder screws and brake pipe joints to make sure that there is no fluid leakage.
  23. Install the wheels, and drive car for a short distance (between 1-2 miles to make sure that brakes are operating properly.
