In this post we look at a key safety feature of your car: the ABS (Anti-lock Braking System). Find out what ABS is, how it works and what to look for if there’s a fault.
What is ABS (Anti-lock Braking System)
ABS (Anti-lock Braking System) is a crucial safety feature of any modern car. It helps stop your car going into a full skid by momentarily releasing braking pressure on one or more wheels.
Every wheel in a modern car has an ABS sensor on it. These sensors constantly monitor the speed of each wheel on your car independently.
In normal driving conditions all the wheels should be turning at the same speed.
What Does ABS Do?
Your car will go into a skid any time one or more of your wheels lock.
This can happen in any driving conditions if the brakes are applied hard and fast. But a skid is much more likely in slippery conditions. Mud, ice and snow mean your wheels are much more likely to lock and send the vehicle into a skid.
The Anti-lock Braking System on any modern car will use the sensor information to to pick up that one wheel is slower. When this happens, the antilock braking system will automatically release the wheel or wheels temporarily to prevent the car going into a skid.
How to Know if There is a Fault with Your Car’s ABS
When the Anti-lock Braking System is working properly, it will probably feel like the brake pedal is momentarily pushing back on your foot instead of resisting. This is perfectly normal and nothing to worry about.
Another way to know that your ABS has engaged to prevent a skid is a juddering sensation along with a noise like a machine gun going off.
However, if you detect this happening on a dry day on a dry road with normal braking, then there may be something wrong with the ABS.
Unless you’re braking to stop suddenly, in an emergency for example, then your wheels shouldn’t lock. If the ABS kicks in during normal driving conditions then it may be faulty.
If you do suspect that there’s a problem with the ABS, please don’t panic. This is not an indication that your brakes will fail. Only that there is an issue with the Anti-lock Braking System.
