What Is ABS In A Car? Let's Find Out.

Anti-lock braking system (ABS):

An anti-lock braking system in a car can prevent your car’s brakes from locking. This system was first introduced in 1950 and used as an anti-skid solution for aircraft. In 1970, it was installed in cars. We also know it as an anti-skid braking system.

Nowadays, this system has become an essential part of every vehicle. It can help you control your steering wheel and traction control.

When you apply pressure to your car brakes and your car wheel stops turning, your car skids. This can cause losing control of your car and would be too dangerous if you drive at a high speed.

When you have an anti-lock braking system in your car, it will prevent your car from skidding. This means you have control of your car and can park it safely, facing no accident or injury.

This system also increases your brake pads, clippers, wheel, and tire life span.

Components of anti-lock braking system:

ABS has four major components. Here is the detail.

Speed sensors: The job of these speed sensors is to monitor how fast the wheels are rotating.
Valves: These valves in the brake line allow, block, and release pressure on the brakes in three different positions.
Pump: These pumps are filled with hydraulic fluid and apply pressure to the brake, drums, or calipers whenever needed.
Electronic control unit: The electronic control unit (ECU) is an important part of an ABS. It works like the brain of the ABS and gets data from the sensors to decide whether to pump the brakes.

What is ABS in a car?

An ABS is an important part of the car’s electronic stability control (ESC).

ABS constantly monitors the sensors of each wheel of the car. If it finds significant and sudden pressure on the brakes. Then an ABS will relax the brakes, stopping the wheels from locking. It also prevents the car from skidding, and the driver won’t lose control of the steering.

ABS Work Stages

ABS works in three stages.

Wheel sensors detect locking or skidding.
ABS pumps the brakes.
Push the brake paddles.

Do anti-lock braking system effective?

The ABS in the car is an important invention in the auto industry, and now it’s a vital part of vehicles. It has many advantages.

Below are 4 benefits of anti-lock braking systems:

There is less chance of fatal accidents when a vehicle has ABS.
An ABS decreased the chance of frontal collision on dry and wet roads.
A vehicle with ABS rarely strays from the road ahead.
In an emergency, a car having ABS can stop at a far shorter distance than a car without ABS.

Issues with ABS:

1) Malfunctioning in the ABS module

An ABS in a car shares a few important parts with the other system of it, like the traction control system.

The role of the traction control system in a car is to keep all the wheels moving smoothly on the road. If it finds that one wheel is not rolling smoothly, it will cut the power from the engine until it moves steadily.

An anti-lock braking system and the traction control system share a self-diagnostic system and control module. Once in a while issue with traction control can cause the light of ABS to come on, and sometimes, there is an issue with ABS which needs to be fixed.

2) Low oil in reservoir:

The brake system of a car is hydraulic. In this system, a power cylinder pressing a fluid to close the brake pads stops a car. For this consistent and constant level of fluid is required in the brake system.

Because of leaks, the level of fluid would be low, and brakes won’t be able to function properly. A car computer will find this issue, and the light ABS will turn on.

To fix this problem, you need to visit a mechanic immediately.

3) Broken wheel speed sensors:

Wheel speed sensors are designed to tell the computer how fast each wheel turns.

If the car computer finds an irregularity in the speed, then traction control will make amendments and shift the power to another wheel.

If the speed sensor gets dirty, it can’t give the proper information, and as a result, the light of the anti-lock braking system will be on.

4) ABS is turned off:

There is an option in a car to switch off the anti-lock braking system, and as a result, the light of this system will turn on, so ABS is not working. In this situation, you can check if you accidentally turn off this system.

If you can’t find where to switch it on, you can consult to owner’s manual or a car mechanic.

A car without ABS, what will happen?

In old model cars, an anti-lock braking system wasn’t installed, and there is no legal requirement that you must have a car with ABS.

If your car skids, you must pump the brakes as quickly as possible.

Did you know? When you pump, the brake paddle quickly to make your car stop. This process is called cadence braking.

Below are a few steps we need to follow if you don’t have ABS in your car.

Slow down your car: First, you must slow down your car as much as possible before moving the steering wheel.
Take your foot off from the accelerator: Then take your foot off of the accelerator pedal, and if you’re in a manual geared car, push the clutch down
Hit the brakes – push the brakes with as much pressure as possible until you can feel your wheels lock, then release the brakes
Pump your brakes – take your foot off the brakes, then reapply the brakes. This replicates the ABS braking method.
