What is the ABS block


The ABS block: a Bosch invention


For the record, the ABS system has been around since 1920 in the airline industry to prevent airplanes from skidding on landing. The function of the ABS block in a car is to prevent, during emergency braking, the wheels from locking.

The ABS block


In a Mercedes R-Class W251 car ABS block, we distinguish in particular...


The hydraulic unit

It is composed of several elements including:


  • Pressure accumulators which are tanks of pressurized gas used to provide a large flow for a short period of time.
  • The electronic distributor that modulates the pressure on the rear wheels.
  • Solenoid valves with a presence of ABS regulation on the rear wheels.

The hydraulic motor

It uses the flow of oil that is pushed into the hydraulic circuit by a hydraulic pump and transforms it by a rotary motion to drive another device such as for example the differential or the fan, etc.


The ECU

It is the part that receives the signal that comes directly from the brake pedal.
