What is the ABS block?


The ABS block: a Bosch invention


The ABS has been mandatory in Europe since 2003. It works through sensors, a computer and a hydraulic control system. The purpose of a vehicle's ABS block is to prevent, during emergency braking, the wheels from locking.


Focus on the ABS system


The ABS block is an accessory to the general ABS system. There are for the brand Mercedes C-Class W203/S203/CL203 ...


  • Magnetic targets: they are, depending on the vehicle models, integrated into the wheel bearings.
  • The ABS block: more details below.
  • The wheel speed sensors: there are 2 types, active sensors operating through electronics, which are supplied via a voltage determined by the ABS computer and passive sensors.

The ABS block


In an ABS block of the Mercedes C-Class W203/S203/CL203 model, we observe, among other things...


Hydraulic unit

Here are some of the elements that make it up...


  • Pressure accumulators, which are none other than pressurized gas reservoirs that can hold a variable volume of a pressurized liquid.
  • The electronic brake force distribution, which is an additional function managed by the ECU.
  • Solenoid valves with a presence of ABS regulation on the rear wheels.

The motor driving a hydraulic pump

It transfers hydraulic energy into mechanical energy.


The ECU

Each time a wheel locks, it controls the solenoid valves and the hydraulic pump.
