ABS (anti-lock braking system) is now standard on many vehicles. Its purpose is to prevent the wheels from slipping during sudden braking. It is worth remembering that, like all parts of your car, it can be damaged. In this case, you will be able to notice the appearance of a warning light on the dashboard. However, it is good to remember that there are several symptoms that may indicate damage to the system. It may be a characteristic jerking while braking or the lack of release of the brakes after releasing the brake pedal.
Causes of an ABS failure
There are many different elements that can fail in the ABS system. The engine of your car generates various types of vibrations which affect all the mechanical components. The cause of the ABS system failure can be corrosion or incorrect soldering of connections. In addition, the ABS system may overheat, and inappropriate protection of the system elements may lead to the penetration of moisture, which may cause functional problems of the ABS unit. Mechanical parts in the engine are often affected by water, snow and additionally road salt. All of this leads to corrosion, and the gasket can also be damaged. On some vehicles the ABS control unit is located at the bottom of the engine, behind the bumper, which is conducive to water and salt depositing, leading to corrosion within a few years.
Defective ABS pump: symptoms
The ABS pump is a very important part of the whole system as it is responsible for adjusting the pressure in the brake system. The pump is connected to a number of different sensors at the wheels and is also connected via hydraulic lines. There are therefore many components that could potentially fail, so if you notice any irregularities in the operation of the ABS, you should immediately go to a trusted garage. A pump failure can cause lack of pressure in the hydraulic system; then the brakes stop working. In addition, problems may be manifested by a characteristic jerking sound when braking, which will indicate an irregular supply of fluid by the pump. In addition, the brakes may be locked, which could indicate a problem with the controller, which is not receiving information from the brake pedal sensor.
