Why Do Cars Need Anti-lock Braking Systems?

[DiJudah]

Cars are equipped with anti-lock braking systems (ABS) to achieve faster, safer, and more convenient deceleration and stopping. When a vehicle without ABS brakes hard at high speeds, the wheels may lock up (stop rotating) and slide on the road surface, reducing the friction coefficient between the tires and the ground, which can easily lead to skidding and potential danger. More details about ABS are as follows: 1. The ABS light briefly illuminates for a few seconds when starting the vehicle: The light turns on when the ignition is switched on or the engine is started, indicating the system is undergoing automatic detection. Once the detection is complete, the light turns off. 2. ABS activates when the brake is pressed hard in an emergency: During emergency braking, ABS prevents wheel lock-up, enhancing the safety of the vehicle during sudden stops. 3. A constantly lit ABS warning light indicates a system malfunction: If the car can still rely on conventional braking while driving, but the ABS warning light remains on, it suggests a fault in the ABS system. Professional diagnosis with specialized equipment is recommended to identify issues such as problems with the tone ring, sensors, or wiring.
