What happens when the ABS fails?

ABS failure light will illuminate, anti-lock braking function will be disabled, and brake pads may fail to reset. Here are some key details about ABS: Introduction: The Anti-lock Braking System (ABS) automatically controls braking force during vehicle deceleration to prevent wheel lock-up, maintaining optimal wheel slip ratio around 20% for maximum road traction. Functions: 1) Maximizes braking efficiency by reducing stopping distance and time 2) Prevents skidding and loss of vehicle control during emergency braking 3) Maintains steering capability during hard braking 4) Minimizes tire wear by preventing excessive friction with road surfaces.
The most dangerous aspect of a faulty ABS is that the wheels lock up completely during emergency braking, instead of pulsing to prevent skidding as they normally would. This can cause the vehicle to skid uncontrollably, with the steering wheel becoming unresponsive, significantly increasing the risk of rear-end collisions or rollovers—especially in rainy or snowy conditions. The ABS warning light on the dashboard typically illuminates to alert you to a system malfunction. Common causes include sensors clogged with mud or dust, aged or broken wiring, or a burnt-out control module. As someone who frequently drives on highways, I recommend not delaying when the light comes on; take the car to a professional repair shop immediately for inspection. Additionally, avoid sudden braking and high-speed turns during normal driving to prevent accidents. Regularly cleaning the sensor areas near the wheels can prevent many issues—after all, safety should never be taken lightly.
When the ABS malfunctions, the brake pedal feels strange—stiff with no elastic feedback. Normally, ABS causes the pedal to pulsate a few times during hard braking to prevent wheel lock-up, but a faulty system fails to do this. Once the wheels lock, the car slides forward uncontrollably like skating on ice, making it impossible to steer. I remember once braking hard at a red light on a city road—the car slid straight for several meters, nearly causing a rear-end collision, which gave me a cold sweat. Possible causes include oil-contaminated sensors or corroded circuits. It’s advisable for drivers to stay vigilant. If the ABS warning light comes on, don’t ignore it—schedule an inspection as soon as possible. While driving, slow down and leave extra braking distance to avoid accidents.
