I have an echo brake which I have just bath bled. As soon as I move the lever off bike the cyclinders move. So as far as I know the bleed seems to be good.
I have set the pads up close to the rim, close enough for me to be unable to slide a 1p in that gap.
However when pulling the lever it comes all the way to the bar with almost no resistance as demonstrated in the linked video.

Any ideas on what could be the problem?
