“EBD” is also sometimes called “Dynamic Rear Proportioning” or “DRP”. When a vehicle brakes, weight shifts forward so that the front wheels are carrying more weight than the rear wheels. As weight is removed from a tire, its ability to grip is reduced. Under braking, since the rear wheels are carrying less weight, they are more prone to skidding (locking up under braking). This is bad. Very bad. Some people expect that locking up the rear wheels should be preferable to locking up the front wheels. After all, with the front wheels unlocked, a driver can still steer.
