The ABS block

Let's look at the non-exhaustive structure of the ABS block of the Citroen C1 model:

The hydraulic motor

It transfers the hydraulic energy into mechanical energy.

The ECU

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

The hydraulic unit

Many components make it up including:

• Solenoid valves that regulate the brake pressure of each wheel.
• Pressure accumulators which are none other than pressurized gas reservoirs used to provide a large flow rate for a short period of time.
• A hydraulic pump whose action ejects the fluid accumulated in the accumulator to the master cylinder, which prevents the pedal from depressing.
