Understanding the ABS Block Principle

The ABS Block: A Bosch Invention

For the record, anti-lock brakes have been around since 1920 in the airline industry to prevent airplanes from skidding on landing. In case of emergency braking, the ABS block ensures that the driver keeps control of his car. Because locking the wheels in such a situation would cause a skid on the road.
