The action comes in the form of releasing pressure from the braking circuit when it detects extreme and rapid deceleration in any of the four wheels in order to make sure that the driver maintains control over the steering during panic or emergency braking. For example if the wheels of a vehicle are on snow as well as asphalt then in case of emergency braking the ABS will monitor the speeds and eventually the EBD system will release less pressure for wheels on snow and more pressure for wheels on asphalt to prevent wheel lock-up.

The braking system will work more swiftly when there is sudden braking if it is equipped with the BA feature. This system works, thanks to the ECU sensor which will detect emergency braking by the driver.
For example, when the driver steps on the brake pedal deep enough, the ECU will detect that the car is in an emergency situation and therefore the braking power will be increased.
With ESC, sensors on the wheels can detect slippage and braking. If something strange is detected by the sensor, then the ESC system will re-adjust. For example, if the steering angle suddenly changes or if the tires are detected to lose traction when taking turns, then the ESC will reestablish the car. It automatically adjusts the brake force depending on conditions to make sure that the front and rear axles yield the best braking force possible without the wheel locking up.
This systems work in tandem with ABS using an electronically controlled valve which diverts hydraulic pressure to the front and rear axles. EBD offers significant braking durability under any conditions and is not dependent on ABS to operate. As the name suggests is responsible to assist the driver in emergency stop situation.
If you have been through a situation where you had to attempt an emergency stop, you might have felt like jamming the brake pedal all through the floor. This is where Braking Assist steps in. Brake assist converts that mild pedal pushes to a complete halt. A sensor attached to the brake pedal triggers the brake assist system to detect when the driver is attempting to stop in an emergency situation and applies full braking pressure until the car comes to a complete halt.
Anti-lock braking system prevents wheel lock up on a wet sleety surface or while panic braking. Sensors on each of your brakes check for wheel lock up and release and mash the brake discs in a matter of microseconds.
Other than the ABS system mashing the brakes and preventing a lock up, ABS also allows you to steer under hard braking. While driving in monsoon, poor visibility in heavy rains could cause other motorists to brake suddenly in front.
ABS system would allow you to actually change your lane safely against the vehicle in front. So, in a car without ABS, in case if the brakes are slammed for too long too hard, the chances of the wheels locking up are always a surety.
And when the wheels do lock, they will stop turning before the car can come to a halt and this in turn causes loss of the directional control of the car. In monsoon, these chances are highly possible and the best way to keep control is to adhere threshold braking, where you brake hard, take the foot off the brake pedals slightly and then repeat till you can stop the car.
But in these panic situations, it is difficult to keep these in mind and opt for a ABS loaded model. A normal ABS system consists of four major components - speed sensors on each wheel, computer controlled valves on each brake on the hydraulic lines , a pump for restoring hydraulic braking pressure and an electronic brain. So when the electronic brain senses that any wheel is decelerating quicker than the others through the sensors, it adjusts the braking pressure of that wheel.
