An ABS block, what's it for?

Car stability thanks to the ABS block

It's not always known, but the ABS system was first developed for airplanes in the 1920s: it was necessary to prevent skidding on landing. The ABS block regulates the pressure of the hydraulic fluid that travels from the pedal to the brake calipers. Thanks to a sensor, installed on the wheels, the ABS block can thus release the pressure on the locked wheels, to give back the control of the vehicle's trajectory to the driver.
