Hello,
I use A hose and a can with some fluid in it. Hose is set below the fluid Pushing slow is all is required. Bubble appear below the fluid. Letting the brake pedal go sucks fluid back, no air. The color tip on the clear hose is a fitting. It came with a master cylinder that I replaced last year. Same Idea, and doing the master cylinder on the bench , sure makes the rest of the job a lot faster. It has worked for me for many moons.......
