Fiat 500 - Repair abs pump

Principle of the ABS block

The ABS block and road safety

For the record, the ABS system was first developed for airplanes in the 1920s: it was necessary to prevent skidding on landing. The purpose of a vehicle's ABS block is to prevent, during emergency braking, the wheels from locking.

A valuable assistant: the ABS system

The ABS block is an accessory to the general ABS system. There are in Fiat 500 ...

• The wheel speed sensors: there are 2 types, the active sensors operating through electronics, which are powered by a voltage defined by the ABS computer and inductive sensors.
• The ABS block: more details below.
• The magnetic targets: they are represented as a series of north and south poles. The alternation of the poles varies the output signal.

The ABS block

The ABS block of the Fiat 500 model is made up of the following elements, among others:

The hydraulic unit

Here are some of the elements that make it up:

• A hydraulic pump, whose action allows the liquid stored in the accumulator to be moved to the master cylinder, which prevents the pedal from sinking.
• Pressure accumulators, which are none other than pressurized gas tanks that can hold a variable volume of a pressurized liquid.
• Solenoid valves with a presence of ABS regulation on the rear wheels.

The hydraulic motor

It is a body 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

It collects information that emanates from each of the wheel sensors.
