BMW X4 F26 - Repair abs pump

Principle of the ABS block

The ABS block: a Bosch invention

For the record, the ABS system was first developed for airplanes in the 1920s: it was needed to prevent skidding on landing. The ABS block regulates the pressure of the hydraulic fluid that travels from the pedal to the brake calipers. Thanks to a sensor, installed on the wheels, the ABS block can thus release the pressure on the locked wheels, in order to give back the control of the vehicle to the motorist.

The ABS system to prevent wheel lockup

Before talking about the ABS block, it is necessary to understand the ABS system entirely. We can observe for the BMW X4 F26 brand ...

• The ABS block: how is it composed? This is what we will find out ...
• The magnetic targets: they come in the form of a series of north and south poles. The alternation of poles varies the output signal.
• The wheel speed sensors: there are 2 types, active sensors that are connected to the ABS computer via a cable and inductive sensors.

The ABS block

In an ABS block of the BMW X4 F26 car, we observe in particular:

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 the gearbox or another pump, etc.

The hydraulic unit

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

• A hydraulic pump that prevents the pedal from sinking during ABS control.
• Pressure accumulators which are none other than tanks of pressurized gas used to provide a large flow for a fairly short time.
• Solenoid valves with a presence of ABS regulation on the rear wheels.

The ECU

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