An ABS block, what's it for?

Definition of ABS block

It's not always known, but the ABS system was first developed for airplanes in the 1920s to prevent skidding on landing. The ABS block controls the deceleration power of each wheel by adapting the level of pressure applied. Because too much pressure can cause the wheels to lock.
