Peugeot 4008 - Repair abs pump

Focus on the ABS block

The ABS block: a Bosch invention

It's not always known, but anti-lock braking was first developed for airplanes in the 1920s to prevent skidding on landing. The ABS block limits the braking power of each wheel by adapting the level of pressure applied. Because too much pressure on the brake pedal may cause the wheels to come to a complete stop.

The ABS system to keep the car under control

Before explaining the ABS block in detail, it is important to understand the entire ABS system. There are for the Peugeot 4008 model ...

• The wheel speed sensors: there are 2 types, passive sensors consisting of a coil among other things and active sensors.
• The ABS block: more details below.
• The magnetic targets: they generate signals read by the sensors, which transmit these signals to the ABS computer.

The ABS block

The ABS block of the Peugeot 4008 model consists in particular of the following elements...

The motor driving a hydraulic pump

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 informs the driver of a malfunction by lighting up a specific lamp on the dashboard.

The hydraulic unit

It is made up of various elements including:

• A hydraulic pump whose action moves the fluid stored in the accumulator to the master cylinder thus preventing the pedal from depressing.
• Solenoid valves that limit the pressure of the brakes of each wheel.
