As has been said, most modern high performance jet aircraft with higher take off speeds have this system. On the A320 family, all the wheels are braked. The reason for this is that the wheels rotate at a high enough speed that centrifugal forces make the tyres expand enough that they could prevent the wheels entering the bay correctly. The A320 ground air logic enables the normal braking system to stop the main gear wheels rotating, and a meatl snubber band in the "roof" of the nosegear bay slows the nosegear. The Fly By Wire system will self check the Autobrakes/Anti skid system on gear deployment. Just fyi., if the brakes do need cooling the A320 may be supplied with brake fans.

Hope that helps.
