Any Dot 5 users here?

I have always recruited one of my kids to work the pedal. My experience with the "mity-vac" or other vacuum bleeders has been mixed at best. You foot can develop a whole heck of a lot more pressure and flow which will push a bubble through a line or around a corner. Also you will pull in a lot of bubbles around the threads of the bleed screws, so it will look like you are getting a lot of air out of the system.

I've never had much problem with air getting into brake fluid. Always use fresh stuff, pour slowly and don't "Shake well before using". Any air will come out of the fluid in a couple days so a re-bleed might be needed in a worst case scenario.
