So two days ago I rolled into work with no brakes until nearly the floor. After work the brakes worked perfectly again. The following day I did 40 mins of driving with perfect brakes but once again after work I had very little brakes. I have not lost any brake fluid so no lines have burst. Any ideas?

dragging brake + water in brake lines = boiling?

Also a MC that is bypassing internally but not leaking into the booster can do this

It's not that freaky early ABS system is it?
