This is going back a few years, but as I recall, nose wheel braking (note spelling) was an option Boeing originally offered to 727 customers who operated into high/hot airports with relatively short runways. Obviously, under such conditions, the actual touchdown speed can be much greater than bugged IAS, leaving a great deal of energy to be dissipated by the brakes.
The combination of high/hot airports and short runways are most commonly found in South America and parts of Africa, which, coincidentally, is where most of the airplanes that were originally equipped with nose wheel brakes were operated. In North America, however, the highest and hottest airports (DEN, PHX, TUS) are also served by the longest runways. Hence, no need for the added weight and complexity of nose wheel braking.
I recall flying a few 727's that had nose wheel brakes installed, but don't think I ever flew one that had them operable.
Nose wheel breaking, on the other hand, is a phenomena that seems to be restricted mostly to the Airbus A320 series of airplanes, about which I will defer to those with some first-hand knowledge.
