Automakers have now begun to install better safety devices on cars and vehicles. Would you believe it if we said that when vehicles were first invented, there were no seat belts for both passengers and drivers? But now car manufacturers have begun to install airbags for individual seats. Just like that, cars now have ABS sensors for better braking.

Here in this article, we will discuss the meaning of ABS sensors. ABS stands for the anti-lock braking system. After ABS was introduced in the automotive industry, the braking system of cars has become more efficient and very safe.

This article will cover all aspects of ABS sensors. For example, what is an ABS sensor? What are its ingredients? Also, what is the workflow of the ABS sensor? And, we will discuss the importance of ABS sensors in cars.

ABS Sensor Story

In older cars, there are disc brakes. In a disc brake system, the brake locks the disc as soon as you apply the brake. Because of this, the braking system will become very dangerous if you are at high speed. Because if you press the accelerator and the system locks the brakes, there is a high chance that your car will slide on the road. Skateboards are difficult to control and there are many cases of accidents occurring after cracking the discs.

This is why car manufacturers have introduced ABS in cars. This brake system is also known as the anti-slip brake system. Because the car will not skid after braking with ABS. The story of the invention of ABS is quite intriguing, as it was first used on airplanes. ABS had a foothold in airplanes in 1920, but it took manufacturers another 50 years to bring it into cars.

ABS Sensor The Components

There are five main components of the ABS sensor. For the ABS system to work properly, all components must work in sync and properly. The five ingredients are:

Speed ​​Sensor:

It is the most important component of ABS. This sensor actually tracks the speed of each vehicle. And then these sensors send the logs to the ABS controller. And then the controller prevents the wheel from drifting by applying only the necessary force to the brake. You often notice that there is a coin-like ring in your wheel and a small coin wrapped in a coil. It’s a magnet. These two components work together to create an electric field through which the sensors can record the vehicle’s speed.


Valves in the ABS help maintain pressure. When you step on the pedal, some pressure is released from the pedal. The job of the valves is to control this pressure. In the event that you press the brake pedal very hard, the valve controls additional pressure on the brake.


The job of the pump is equally important. It restores the pressure that was released by the previous valves. It restores the pressure in the hydraulic system.

Brake Fluid:

Brake fluid helps put pressure on the brake after pressing the pedal. Brake fluid transfers power from the pedal to the brake. As we all know, brakes generate too much heat, and that’s why you have to spend money to change brake pads. In addition, brake fluid has a high boiling point due to heat.

Remote Control:

This is part of the brain of the ABS sensor. The controller records all data from the individual wheels and then coordinates the amount of pressure and wheel speed. If the controller receives a signal that the pressure on the brake is greater and may cause the wheel to skid. It then depressurizes accordingly to avoid slippage.

Working Process

When you depress the brake pedal, brake fluid (in the fluid chamber) transfers force to the brake. The force in the brake fluid puts pressure on the wheel and the wheel begins to lock. During wheel locking, the controller monitors the wheel speed and controls the required pressure. And when the wheel reaches a safe speed, the ABS system blocks the wheel completely. And once the car stops and you release the pressure from the brake pads. The pump then delivers brake fluid to the hydraulic chamber.

Amazingly, all these processes happen in just a fraction of a second. Thanks to modern technology, high-speed braking is now risk-free. Even though the brakes are good, you have to be very careful while driving. Keeping vehicles under human control is the ultimate responsibility.

There are different types of ABS working processes, it depends on the type of ABS on the vehicle. The above discussion of the ABS workflow is the basic workflow. However, there are four different types of ABS sensors. That is:

  • Four channels

  • channel three

  • dual channel

  • single channel

ABS Sensor  Importance

It is very important to have an ABS sensor in your vehicle. We all know that roads are full of uncertainties. There are many natural creatures and also irresponsible humans who can jump in front of vehicles from nowhere. ABS ensures their safety as well as your safety. In addition, there is an unknown road error that you will encounter while driving. For example, you don’t want to add budget to the cost of replacing your bumpers, as if you didn’t have ABS. Then you will not be able to stop before unwanted speed bumps and potholes. Just like these, ABS is also very useful in off-roading. With the onboard ABS sensor, you can control your vehicle perfectly.

ABS in cars also helps control traction very well on the road.


If you buy a new car or replace your old car with a new car. Make sure you have a vehicle equipped with an ABS sensor. Not just for your safety, but for the safety of others. If you choose four-channel ABS, it doesn’t get any better than this. Avoid choosing single-channel ABS sensors as they are much less effective for cars.
