ABS, known as the anti-lock braking system, is tasked with maintaining the safety of passengers by preventing tire closure while using brakes.
In this way, the control of the steering of the vehicle can be maintained and its slippage prevented from being sliding as a result of the tire lock.
In addition, there is a warning light on the dashboard that will work if there is something wrong with the system.
This light should be taken into consideration.
because it is an early warning sign that your brake system should be checked immediately.
When the ABS light is activated on the dashboard of your car, it indicates a malfunction in the anti-lock brake system.
This means that if you need to press the brake pedal quickly to stop your car, you may not stop as fast as it used to.
The main function of the anti-lock brake system is to keep your tires on the road while you press the brakes.
In this way, the tire is not locked or slipped uncontrollably on the road during braking.
This is especially important if the road is slippery or wet.
How does ABS work?
As we mentioned earlier, the function of the anti-lock braking system is to prevent the tires from closing during the braking while still allowing the car to be steered.
When the brakes are closed, it stops the tires from spinning.
However, the car is heavy and may not stop right away and may start slipping uncontrollably.
The ABS system uses tire speed sensors to determine when the tires are stopped but the vehicle is still in motion.
The sensor will send a message to the ABS unit .
that determines when the vehicle slides and will automatically activate the ABS.
Under emergency braking, the driver will feel the pressure and the pulsating feel through the brake pedal when the ABS is active.
The anti-lock brake system will release the brake pressure repeatedly and apply to the brakes when you quickly apply the brake.
This allows the tires to continue spinning while maintaining traction.
In this case the driver must continue to apply the brakes and allow the ABS to make its magic.
What are the causes of ABS failure?
Many causes can lead to ABS failure, this does not always mean that there is a problem with the anti-lock brake system directly .
as there are various reasons behind the lighting of the ABS light for the car.
The main reason is simply when you start your car the computer tests the anti-lock braking system to make sure it is operating normally.
If the computer does not find a problem, the ABS light will turn off quickly.
But if the ABS light remains on, this means there is a problem with the anti-lock braking system.
There may also be a problem with the sensors or other components connected to the ABS system.
Sometimes you may drive your car and the ABS light will suddenly appear too.
However, here are 5 common causes of ABS failure:
1 – Low brake fluid
The brake fluid has a great relationship with the control of braking pressure in the anti-lock brake system.
Brake fluid leaks may occur from the Brake reservoir, connections, or any part of the system, which causes fluid levels to drop.
This will definitely cause a defect in the ABS and an ABS warning light will work on the dashboard.
Also, if the brake system is not deflated, it will cause the same problem.
2 – Speed sensor malfunction
There are speed sensors built into the axis of each tire .
that calculates the rate of movement, then this information is transferred to the anti-lock braking system.
If it turns out that at least one of the tires is moving too slowly .
the anti-lock brake system will increase the pressure of the brake fluid to allow the tire to move at a normal speed.
But when there is a malfunction in the speed sensor.
the anti-lock brake system will detect this and cause the warning light on the dashboard to illuminate.
3- The ABS unit is damaged
Over time, the anti-lock braking system unit begins to wear, ending the default use period.
This is actually one of the most common causes of an anti-lock brake problem.
If the unit is corroded, you will not be able to obtain information from the tire speed sensor.
As a result, the ABS light appears on the dashboard.
It does not take a lot of wear until this happens as well but you will need to replace damaged wires, connections and if necessary you may have to replace the unit completely after this happens.
4 – The hydraulic pump is damaged
If one of the car’s tires moves at a different speed from the other tires .
the tire speed sensor detects this and transfers the information to the anti-lock braking system.
When this happens, the system will activate the hydraulic pump to increase the amount of brake fluid pressure.
This will allow the tires to maintain traction while touching the ground.
Unfortunately, hydraulic pumps tend to wear and tear after years of use.
This will definitely turn on the ABS light which means that you will need to replace the pump immediately.
5- ABS fuse damage
Like any electrical system or component, its anti-lock braking system will have a fuse.
So before trying to replace expensive parts or spend some time troubleshooting, be sure to replace it.
A quick check in the fuse box can save you time and money.
Can the car be driven when the ABS light appears?
Just because your ABS light appears does not mean that you cannot drive your car.
In fact, you will still be able to press the brake pedal and slow the car.
However, your ability to control the vehicle with strong braking will be limited .
as you run the risk of closing the tires under severe braking.
Tire lock greatly increases stopping distance and prevents you from steering until the front tires restore traction.
What you need to do is drive carefully to the nearest mechanic after the ABS light illuminates.
Use the brakes slowly when necessary but avoid braking aggressively, if you can do this everything will be fine.
The only circumstance when you should not try to drive your vehicle is if the brake system light turns on while the ABS light is on.
The brake system light indicates a much larger problem with the braking system, a problem that may limit your ability to stop the vehicle.
