ABS
The ABS, as it is commonly called is the abbreviation for Anti-Lock Braking System. This is a feature that many of the newer cars come fitted with. But it was not always the case, and still is not the case with several makes.
What is the ABS' Before that question is answered, it is perhaps necessary to look at the "brakes". But simply, a brake is a system device that reduces speed or stops a moving object (in this case your car) by creating a force in the opposite direction.
Insufficient pressure (brake torque) in the brake system causes "wheel lock" while the vehicle is moving above 80 km/h on a dry paved road surface. Premature "wheel lock" occurs from turbulent shock waves being generated by the uneven braking surfaces (rotors or drums contacting the pads/shoes), vibrating or slapping against the hydraulic pistons in either the clippers or the wheel cylinders.
The force of these shock waves can be easily 100 times that of brake torque or the maximum pressure exerted on the rotating brake components. These shock waves have more than enough force to lock the wheels.
Wheel lock occurs when brake torque forces exceed tyre grip forces. The impact would be much
