What is ABS?
Pet
ABS is a safety feature designed to prevent your car’s wheels from seizing. With the car still moving on the same relatively small area of tyre, you’d lose traction.
This means the car would skid, regardless of where the wheels are facing.
What ABS does is prevent the wheels locking-up. This ensures you still have some control of the car.
The wheels will continue to rotate, and the car can move in whatever direction they’re facing.
How does ABS work?
The anti-lock braking system is part of the car’s electronic stability control (ESC).
The ESC also helps prevent problems such as oversteer or understeer and is linked to the engine control unit (ECU), which is effectively the car’s brain.
What the ABS does is constantly monitor the sensors on each of the car’s wheels.
If it detects a sudden and significant pressure on the brakes, the ABS intermittently relaxes the brakes to stop the wheels from locking.
