How does ABS work?

• A. Keeps braking force constant
• B. Increases braking distance
• C. Enhances the ability to steer while braking hard
• D. Removes ABS features when wheels slip

Answer: (C)

ABS is about keeping you in control during a hard stop by preventing wheel lock. When you brake hard, the system watches how fast each wheel is turning. If a wheel starts to slow down too much and risk locking, the ABS controller eases off the brake pressure on that wheel, then quickly presses it again. It repeats this rapid press-and-release cycle to keep the tires rolling just enough to avoid a skid. Because the wheels stay turning, you can still steer, which lets you steer around obstacles even while you’re braking as hard as possible. Think of it as maintaining a small amount of slip—enough to keep traction and direction—rather than squeezing brake pressure to a constant level. On typical dry pavement, ABS helps you stop safely and maintain steering; on slick surfaces you’ll still feel the pedal pulsate as pressure is adjusted, but the goal remains to preserve steering control during braking.
