I had the same problem with my Vega. I couldn't get the air out no matter much I bled it. The problem was that the air would compress and wedge itself in a spot and never break out. The low pressure bleeder doesn't have enough pressure to compress the air and it gets bled out. I couldn't believe the size of the air bubble when it did bleed out. The brakes were great after that and the front wheels would hold the car for the burn out. Before that it would just roll and it was a pain to do a decent burnout. The bleeder is easy to build and works great. Use a large "C" clamp to clamp it to to master cylinder.
