I don't know what system you have in the USA...but the Euro "brake energy recovery system" has nothing at all to do with the brakes. It simply consists of a special battery, a high output alternator and associated electronics. When you accelerate the alternator is disconnected, when the throttles are closed the alternator is reconnected, if the battery is low on charge the alternator is connected regardless of throttle position, that is essentially it.
