Someone on another post asked a question that was never answered and I find intriguing: are the rear brakes only used for quick and or panic stops? If the Leaf uses mostly regen breaking and regen braking is done by the electric motor through the front wheels, to me that indicates that rear wheel breaking is not normally used. Modern breaking systems have gone to great pains to equalize front and rear breaking to maintain vehicle stability and dynamic traction control (or whatever Nissan calls it) is based on it. I am guessing that in order to maximize regen braking rear wheel brakes are only used in quick stops or when regen disengages. Comment anyone?
