Hydro boost question

[Joyridin]

I am just curious if anybody running a hydroboost set-up has had a line blow? I tried to bleed my master cylinder, but there is no pressure on the hydro unit, so unlike a vacuum booster, the master cylinder doesn't move. I assume the accumulator would work if it had pressure, but after a few pumps, I guess the pressure in it would be released and then you would have no brakes?
