So are you saying that it is not necessary to open and close the bleed valve between pumps?
That is correct. That shit is probably auto industry fallacy. Bikes were mechanical drum brakes until the 1960's say. I have no clue if the biker took the same auto think? It's not how I do it.
Doesn't the lever just swing in and out with no pressure at all after the first pump if you leave the bleed open?
Yes, but think how a bicycle hand pump works. The little hole at the top next to the rod? When the leather washer is pushed by the rod: ----< it seals as it spreads to hold the air from moving back out the little hole, yes? When you draw the rod back up, the seal collapses up the tube, the air in that little hole is like that pump hole, wink-wink 14.7 psi in [liquid form] moves instead. Get it? The bigger hole is the gravity feed/return or as you pull the rod up with leather seal being a two-way-switch. Make basic sense?
Look at how you are moving fluid instead of air. This master is a simple pump moving liquid like we have a well pump now? Same principals, different designs moving liquid and air say. So say we have zero air bubbles thru the threads, we hardly open the nip. We know the nip is open because (1) the fluid is solid going out and (2) when we stop to fill, the hoop in the bleed line off the nip is going to suck fluid back in, because when you start pushing more fresh at the lever, there are no bubbles but fluid moving again and (3) you can close the nipple before the lever reaches the grip: show me the bubbles.
That's how simple the trick is... Take the Old fallacy stretch my threads over and over on every close? No thanks I have an easier way.
