What are the effects of a faulty ABS on braking?
2 Answers
ABS failure prevents the brake pads from resetting. Here is additional information: 1. ABS malfunction: In emergency braking situations, the ABS function will not operate. The ABS system prevents wheel lock-up during hard braking to avoid accidents. 2. ABS braking function: It prevents wheel lock-up, allowing the car to steer while braking, ensuring directional stability and preventing skidding or deviation. It is currently the most advanced and effective braking system in automobiles. 3. ABS working principle: During braking, ABS quickly determines wheel lock-up status based on speed signals from each wheel speed sensor. It closes the normally open input solenoid valve for the locking wheel to maintain braking force. If the wheel continues to lock, it opens the normally closed output solenoid valve, causing the braking pressure on that wheel to drop rapidly due to the direct connection to the brake fluid reservoir, preventing complete wheel lock-up from excessive braking force.
I've been driving for decades, and that time when the ABS failed still gives me chills. I remember slamming on the brakes on a slippery curve, and the wheels instantly locked up, causing the car to spin like it was on ice, nearly hitting a tree by the roadside. The ABS is designed to prevent wheel lock-up and maintain steering control. Once it fails, braking becomes primitive: under hard braking, the wheels may completely stop rotating, leading to uncontrolled skidding, especially dangerous in rain or snow. The braking distance also increases because there's no automatic pressure adjustment, making skidding more likely. I've now developed a habit of heading straight to the repair shop whenever I see the ABS light on the dashboard. Safety is no joke; delaying repairs can lead to major trouble, affecting daily travel safety.
