Question 5116
Which system reduces the risk of the wheels locking up during hard braking?
- The brake booster.
- All-wheel drive.
- ABS.
Show answer and explanation
Correct answer: ABS.
ABS uses sensors to monitor the rotation of each wheel. During hard braking, if a wheel is about to lock, it briefly reduces the brake pressure at that wheel to keep it turning, so you can keep steering the car. The brake booster multiplies the force from your foot, and all-wheel drive distributes the engine's power among all four wheels, but neither prevents the wheels from locking.
