An anti-lock braking system (ABS) address two conditionals related to brake applications. Which is;
- Wheel lockup
- Vehicle directional control
The brakes slow the rotation of the wheels, but it is actually the friction between the tires and road surfaces that stop the car. Without ABS, when brakes are applied with enough force to lock the tires and road surface and will lost the control of the steering while skidding.
By using ABS, it's provides a high level of safety to driver by preventing the wheels from locking which maintains the directional stability. An ABS can do that no driver can do, which is it controls each front brake separately and the rear brakes as a pair whenever one of the wheels start locking. ABS also helps stop a car at a shortest possible distance without wheel lockup while maintaining directional control on most types of road surfaces and conditions.
