Maybe I'm missing something here but I just shove a small diameter tube onto the brake bleeder and let it hang into the catch bottle. Vacuum hose vorks well. The id is small enough that the brake fluid won't drain out of the hose so it prevents air from get back into the bleeder. I crack the bleeder open just a bit - not a full turn. Push the brake pedal with your right hand while looking under the truck at the fluid squirting into the catch bottle. After 5 or 6 full pedal strokes, refill the res' and pump some more.
Nope, you're not mising a thing Bruce, in fact my method above was just how you explained it to me... and worked great.
Corsair just likes to make things more difficult than they need to be
