An ABS block, what's it for?

Definition of ABS block

For the record, anti-lock brakes were first developed for airplanes in the 1920s to prevent skidding on landing. The acronym ABS comes from the German "Antiblockiersystem". It is an anti-lock wheel system that helps to maintain control of the vehicle when sudden braking occurs.

The ECU

As soon as a wheel tends to lock, it guides the solenoid valves and the hydraulic pump.

The hydraulic motor

This is an organ that transforms a flow rate into rotational speed and a pressure into operating torque. The speed of rotation of the motor is proportional to the flow that feeds it.

The hydraulic unit

• A hydraulic pump whose action allows the liquid stored in the accumulator to be pumped back to the master cylinder, which prevents the pedal from sinking.
• Solenoid valves with a presence of ABS regulation on the rear wheels.
• The electronic brake distributor, which has a complementary role managed by the ECU.
