How does an ABS block work?

The stability of the car thanks to the ABS block

Since 2003, the Highway Code requires that an ABS block be installed on every automobile. 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, to give back the control of the vehicle to the driver.
