Does anyone here use a Mighty Vac pump to bleed their brake lines? If so, how long does it take you to bleed all four lines?

I used mine this weekend and it took me at least 30 minutes per wheel to suck out all the old fluid and draw new fluid. Here's my process. I'd pump the device about 15 times, open the bleeder valve a quarter turn, but only a few drops of fluid would get sucked into the container due to vacuum pressure. I then closed the bleeder valve and repeated the process again. I even loosened the filler cap on the master cylinder to see if this would increase the amount of fluid drawn, but it didn't make a difference. Any other way to increase the amount of fluid sucked into the container using a Mighty Vac or is this normal? This process takes takes too much time so I'm seriously considering investing in a set of Speed Bleeders.

 

I use it. Just pump with the bleeder open and let it come out. Takes a little time, but it's a one man job with that pump.

 

OK. Pumping while keeping the bleeder valve open will definitely shorten the process. How about the cap on the MC? Loose or tight? Thanks!
