Principle of the ABS block

ABS block and car control

It's not always known, but anti-lock braking was first developed for airplanes in the 1920s: it was needed 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 wheels that would be blocked, in order to give back the control of the vehicle to the motorist.
