  3. Vehicle Lift
    1. Raise the vehicle on a lift, and make sure it is securely supported.

    NOTE:
    • Do not reuse the drained fluid. Use only new Honda DOT 3 Brake Fluid from an unopened container. Using a non-Honda brake fluid can cause corrosion and shorten the life of the system.
    • Make sure no dirt or other foreign matter gets in the brake fluid.
    • The reservoir connected to the master cylinder must be at the MAX (upper) level mark at the start of the bleeding procedure and checked after bleeding each wheel. Add fluid as required.
    • There are three different methods used for bleeding brake systems. The method shown here is the preferred manual method for removing the air from the system. For pressure or vacuum bleeding, refer to tool manufacturer's instructions included with the tool.
    1. Make sure the brake fluid level in the reservoir tank (A) is at the MAX (upper) level line (B).

    2. Start the bleeding at the driver's side of the front brake system.
      NOTE: Bleed the calipers in the sequence shown.
    3. Attach a length of clear drain tube (A) to the bleed screw (B).
    4. Submerge the other end of the drain tube into a clear plastic catch bottle of brake fluid (C).
    5. Have an assistant slowly pump the brake pedal several times then apply steady continuous pressure.
    6. Loosen the bleed screw slowly to bleed the fluid into the plastic catch bottle. The brake pedal will travel toward the floor as the fluid is bled from the system.

    7. When the brake pedal reaches the floor, have the assistant hold the pedal in that position, then tighten the bleed screw. The brake pedal can now be released.
    8. Check and refill the master cylinder reservoir tank to the MAX (upper) level line. Be sure to reinstall the master cylinder reservoir cap.
    9. Repeat steps  5 thru  8 until the brake fluid in the clear drain tube appears fresh and there are no air bubbles in the fluid.
    10. Repeat this procedure for each brake in the bleeding sequence.
  5. HDS DLC - Connection
    1. Connect the HDS to the data link connector (DLC) (A) located under the driver's side of the dashboard.
    2. Turn the ignition switch to ON (II).
    3. Make sure the HDS communicates with the vehicle. If it does not communicate, go to the DLC circuit troubleshooting.
