An ABS braking system will operate as a conventional braking system under normal conditions. They are similar in design and share many components. The major differences are seen and felt under heavy braking. A pulsation will be felt under foot and the car will be much easier to control compared to its conventional braking counterpart. The system uses various sensors to monitor speed and it has the ability to sense if one or more of the wheels is losing traction. Once the system senses that one of the wheels is losing traction, the system starts to change the braking pressures several times a second. This allows the vehicle to remain in control.
