Mercedes SL R231 - Repair abs pump

Principle of the ABS block

The ABS block and road safety

It was the German company Bosch that developed an early version of the ABS block in the late 1970s. The ABS block controls the braking force of each wheel by adapting the level of pressure applied. Because too much pressure can cause the wheel to lock up.

A valuable aid: the ABS system

The ABS block is a part of the overall ABS system. We can observe for the Mercedes SL R231 model ...

• The magnetic targets: they are in the form of a succession of north and south poles. The alternation of the poles varies the output signal.
• The ABS block: more details below.
• The wheel speed sensors: there are 2 types, the inductive sensors composed in particular of a permanent magnet and the active sensors.

The ABS block

Various elements of the ABS block of the Mercedes SL R231 car to be apprehended including:

The hydraulic unit

It is composed of various elements including...

• Solenoid valves that eliminate the need for a brake compensator.
• The electronic brake distributor, which has a complementary role managed by the ECU.
• A hydraulic pump, the action of which allows the liquid accumulated in the accumulator to be ejected to the master cylinder thus preventing the pedal from being depressed.

The motor driving a hydraulic pump

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

The ECU

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