I used to pressure bleed back when master cylinders were iron. Made a cap with an air fitting on it. For sure the best and easiest way but with today's plastic reservoirs it doesn't seem like a good idea. Old vacuum pump and a Mason jar with a couple tubes soldered in. (pretty much as shown above). The old brake pedal deal never did work for me. Sometimes just leave the bleeder open and let gravity do it would work, usually not. Used to really hate any brake work that opened the system.
Now I hate antifreeze, seems like there is always a seep somewhere undetectable.
