What is ABS Brake System


One of the most often asked topics by drivers is what the ABS in a car means, which has just been mandated. It is a mechanism designed to avoid wheel lock-up caused by weather, road conditions, and other vehicle-related factors.

The primary goal of manufacture is to assure driving safety. If the vehicle speed is not at the required ratios with the accelerometers on the wheel, the ABS system recognizes that a wheel is locked and activates to prevent the wheel from being locked.



When the speed is high, the non-rotating wheel releases its brake and turns again, and again, ABS prevents slippage. The braking distance is also reduced with this technology. All of these steps help to avoid slipping and losing control when driving.

Furthermore, the ABS brake system is sometimes referred to as the ABS brake pad. To properly grasp the role of the ABS braking system, it is vital to first understand the distinction between ABS and standard brakes. These distinctions can be summarized as follows:

  • With ABS, stopping is realized at a shorter distance than the normal system.
  • While the braking distance is extended with ABS, the normal brake is locked in one go.
  • Normal brake slips and stops sooner.

ABS Expansion

What does Abs signify, and why is it vital in traffic safety? The original abbreviation for the ABS brake system, which is required in cars, is “Anti-Lock Braking,” or “Anti-Locking Braking System.” The ABS brake system was invented in the 1920s by the German business Voisin as “anti-lock braking equipment.”

The German business Voisin obtained the patent for the first example using a hydraulic system, with the German number 671975. When Mercedes and BMW began to employ it in regular cars in 1978, its use became widespread, and it eventually became essential for everyone’s safety in traffic in many nations.

What Does the ABS Brake System Do?

ABS’s basic operating premise is to ensure safe driving. It accomplishes this by preventing the vehicle’s hydraulic brakes from locking the wheels. It prevents sliding by adjusting the speed of the wheels and maintaining the driver’s steering control regardless of the road conditions, load, or speed of the vehicle.



When the wheel speed falls on an ice road, for example, the ABS braking system intervenes in the braking force and prevents sliding. A tiny vibration and sound in the brake pedal indicate this.

Motorcycles can also use the ABS braking system. It is referred to as the “brake anti-lock braking system” in this country. It allows the tire to rotate by lowering the pressure on the brake pads, which tighten the tread during braking.

How Does the ABS Brake System Work?

The ABS braking system reduces the braking time in 1/18th of a second, thus protecting the driver’s steering control. This system is managed by an artificial intelligence. In order to understand how the ABS brake system works, it will be useful to first take a look at the parts of the system. In summary, the system works like this:

  • When the brake pedal is pressed, the brake hydraulic oil is formed by the pressure.
  • The resulting oil is transmitted to the existing brake mechanism of the wheels by the ABS control group.
  • The electric pump in the control unit adjusts the brake pressure.

It is possible to understand whether the brake system is working and whether it is present in a large area closed to traffic. If the vehicle can go in the desired direction when the steering wheel is turned by pressing the brake fully while driving in this area, the ABS works and is available.

What are ABS Brake System Parts?

In order to better understand the ABS brake system and to act consciously during a possible malfunction, it will be useful to know what its parts are. The parts of the ABS brake system operated by the ABS electronic control unit are as follows;

  • ABS Control Group

This group includes the electric hydraulic pump, the solenoid valve body and the control unit. The hydraulic oil reaches the brake mechanism of the wheels through the control group. The brake pressure is adjusted with the electric pump.

  • Wheel Sensors

There are ABS sensors on each wheel. These sensors transmit the rotational speed of the wheel to the ABS ECU. According to the signals of the sensors, the vehicle speed, mileage information and wheel speed are calculated.

  • Wheel Rotors

When the driver applies pressure to the brake pedal, a movement in the brake hydraulic oil starts with this pressure. Thanks to these rotors, the control group and hydraulic structure tasks are active.

What are the Advantages of ABS Brake System?

The following are the benefits of the ABS brake system, which prevents the hydraulic brakes from locking the vehicle wheels:

  • It keeps you from slipping on snowy ground.
  • It keeps you from whirling in the rain. In wet weather, spinning allows the wheel that enters the water alone to rotate.
  • It enables steering control regardless of load, road conditions, weather, or speed.
  • It keeps the car from skidding, twisting around, and somersaulting during high-speed stops.

ABS benefits provide safe traffic and driving chances when all of these factors are considered.

What are ABS Brake System Malfunctions?

The lit indication on the vehicle’s information panel indicates an ABS brake system problem. When the signal begins to flash, you must proceed to the authorized service. So, what are the ABS brake system flaws?

  • Blown fuse
  • Speed sensors that are defective or unclean
  • ABS control unit failure
  • Low brake fluid level (On some ABS models, the ABS brake fluid reservoir is separate.)
  • Problems with the connections between the parts, such as looseness and disconnection.
  • Damaged ABS module

If the connections are faulty, repair may suffice; however, if the module is damaged, the entire system must be replaced. Experts generally advised that when going to the service, electrical connections, resistance checks, and voltage be verified. Vehicles with an ABS brake system malfunction or warning notification will not pass the vehicle inspection.

What Does ABS Disabled Mean?

When the ABS light illuminates on the ABS indication bulb, it indicates that the ABS system has been disabled owing to a problem. Even though the conventional brakes work well, the anti-locking system, or ABS brake system, does not function during rapid braking.

Because they utilise the same wheel speed sensors as the ABS system, the vehicle’s Stability Control (ESP/VSA) and Traction Control System will also be disabled.

Even if there is a malfunction, the signal may go off in some situations, but if you see the signal light for an extended period of time, you should absolutely contact support. Because the failure is most likely still happening and other parts could be damaged.

ABS Brake System Prices

Because ABS is standard in all vehicles manufactured after 2012, it is rarely purchased as an add-on. However, if the ABS system fails, spare parts for the ABS part or the entire system are ordered. Vehicles without ABS manufactured prior to 2012, on the other hand, must acquire all of the parts in the ABS version of that car model in order to add ABS.

As a result, the costs of installing an ABS braking system and purchasing an ABS brake system differ. It is also vital to consider the uniqueness of the ABS brake system or its components. All of these parts are available on the internet or via authorized dealers.
