Are anti-lock brakes always activated when you depress the brakes?

No, anti-lock brakes (ABS) are not always activated when you depress the brakes. ABS is designed to engage only during specific conditions, such as when the wheels are about to lock up during hard braking or slippery surfaces. Under normal braking conditions, the system remains inactive, allowing for standard braking performance. When activated, ABS helps maintain steering control and prevents skidding by modulating brake pressure.
