Interesting, so the idea is that would save time vs standing there flicking the levers until the bubbles stop?
Would you do this with the upper bleed port open/funnel attached to allow mineral oil to flow in/bubbles bubble out?
Even the normal burp/lever-bleed instructions, they mention 'flick' the brakes, rather than just squeeze and release. Is there something about the flicking that dislodges air bubbles? Does it like send a little shockwave through the hydraulic system?
