I have some air trapped in my brakes and want to try the long tube method to purge. With the tubes in the resevoir and connected to each caliper nipple, I understand the idea of cracking each nippple open and pumping until the cows come come.
What puzzles me is the idea of injecting air back into the system using this method. Until the lines are full of fluid, won't you be sucking air on each pump of the brakes back throuh the nipple from the empty tubes? I have a motive bleeder but can't seem to get all the air out. It takes a couple pumps to get a hard pedal. New MC All new rebuilt calipers, etc Used the pedal pump and release method Flushed a 1/2 gallon of fluid throuh the calipers Rear vented to .004 Driven the car and repeated the bleeding with motive and two people Yes, the front caliper nipples are pointed up No speed bleeders (IMG:http://www.914world.com/bbs2/uploads/post-419-1182989448.jpg) |

While I'm certainly not an expert in this method, I think the idea is to keep an eye on the brake fluid level while there is air in the tubes. When you start pumping, the air will go into the brake reservoir, but the bubbles will immediately go to the top and out...as long as you don't let the reservoir run dry, you'll eventually have a solid flow of fluid.
