Also there is one other side ABS function. ABS also helps you to maintain straight line braking when your car is on different surfaces, for egg. left side on tarmac, other on mud. In such conditions when braking wheels on more slippery surface would lock quicker than on other, so car would start to spin at that direction. ABS as you all already know has ability to apply pressure to each wheel independently so it applies less pressure on those who are on gripper surface maintaining full control of the car.
