If you had front and rear brakes smoking that makes me suspect the brake free pedal adjustment. If it's just tight enough, as the brakes heat up they will begin to drag. After the first time, did you drive it any kind of distance? Driving some amount of distance gives the brakes more of a chance to get hot, and to start dragging again.

While the hoses may be bad inside, I'd think that all three being bad and causing the brakes to drag at the same is pretty low probability. Not saying it can't happen. Recent...ish replacement of the master and booster is the clue that maybe the brake free pedal is insufficient.
