Flushed it when first got it 3 Years ago thinking about doing it again this winter when get a cold spell up here in North FL which contrary to what some might think, North FL does get cold.. Seen it in the teens now and then .. But below 30 is cold enough for me to do some Bike Work and stay home ..

Never ever bleed out a master that way. Even on a two year old system, it is going to have corrosion near end of cylinder. When you break bleeder at caliper and pull the brake lever or push the pedal, you push the rubber brake cup seal piston into the corrosive. It will probably work but I bet its leaking by.
Keep a eye open on it. I would put a medium amount of pressure on it and hold it for about a minute to make sure pedal or lever does not keep moving.
When you vacuum it, only about 5-8 lbs vacuum. It's very easy to pull air in from outside since a cup seal works with tremendous pressure one way only. Easy to pull air under it the other way.

When she squeezes, I open valve and it drains a little. The handle pulls to grip gently/quickly, and she held it there . I closed valve and then said to release handle. We did this for the 2 reservoirs to drain. The front brakes feel better than ever and fluid is correct type and level. Am I missing something ? Several people, as well as video, performed it this way for simple flush.. In a couple weeks my mechanic will put on new pads and completely clean out system.. Thanks
