Anti-lock brakes should be pressed all the way, unless all 4 tires go into a skid, at which time you have to start pumping. But as long as at least one tire is still rotating, they do the work. This requires a complete iced over road situation, as most of the time at least one tire will still be going.
I feel like we've made good progress in this anti-lock brake thread.
