What is the function of ABS?

ABS function: It can prevent loss of steering control and wheel skidding during emergency braking, ensuring the wheels do not lock up when braking. This prevents the tires from rubbing against the ground at a single point, increasing friction and achieving over 90% braking efficiency. Additionally, it reduces brake wear and extends the service life of brake drums, discs, and tires by up to twice as long. ABS can be installed on any vehicle with hydraulic brakes. It utilizes a rubber airbag inside the valve body to apply pressure to the brake fluid when the brake is pressed, filling the ABS valve body. The airbag then uses an intermediate air layer to return the pressure, helping the wheels avoid the lock-up point.
ABS stands for Anti-lock Braking System. My old car doesn't have this feature, but all new cars come equipped with it. Its biggest advantage is preventing wheels from completely locking up during emergency braking. In the past, slamming on brakes on icy roads would cause the car to skid and spin, which was extremely dangerous. However, ABS maintains tire rotation through rapid pulsating braking, allowing drivers to still steer and avoid obstacles. This is crucial for safety - it's saved my life several times in rain or snow. The ABS system typically uses sensors to monitor wheel speed. When lock-up is detected, it releases brake pressure for milliseconds before reapplying it, creating a pulsating sensation you can feel through the pedal. Remember to regularly check if the ABS warning light illuminates properly. If it stays on constantly, get it repaired at a garage immediately - don't ignore it. In daily driving, ABS helps reduce rear-end collisions and shortens braking distance, but don't rely on it as an excuse to drive too fast.
