ABS
ABS: Antilock Brake System (or Anti-locking Brake System) - enables you to steer whilst keeping the brake pedal full on. Can be felt as a vibration through the pedal when it cuts in. Also useful in stopping in a straight line if one side is on slippery stuff and the other on grippy stuff (non-ABS will tend to spin).
EBD
EBD: Electronic Brake Distribution (or Electronic Brake-force Distributor) - alters how much of the brake force goes to the front and how much to the rear. Cars always have more braking on front as if the rears lock before the front then the car will spin. How much braking you can do with the rears depends on how much weight is in the vehicle so EBD dynamically adjusts this balance. Without it, the manufacturer sets up the balance so the rears don't lock when the vehicle is empty which is less braking than is possible when the vehicle is full.
