Conventional Brake System Bleeding: Bleeding

NOTICE: 

• Do not spill brake fluid on the vehicle; it may damage the paint. If brake fluid does contact the paint, wash it off immediately with water.
• There are three different methods used for bleeding brake systems. The method shown in this procedure is the preferred method for removing the air from the system. For pressure or vacuum bleeding, refer to the tool manufacturer's instructions included with the tool. If you use a commercially available pressure feed bleeder and operate the brake pedal, excessive hydraulic pressure will be applied to the cup inside the master cylinder causing damage. Do not use these methods together.

NOTE: 

• Do not reuse the drained brake fluid. Use only new Acura DOT 3 Brake Fluid from an unopened container. Using a non-Acura 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.

   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.
