Which system in the vehicle helps to prevent wheel lock-up during braking?

The Anti-lock Braking System (ABS) is designed specifically to prevent wheel lock-up during braking. When a driver applies the brakes, especially in emergency situations or on slippery surfaces, ABS monitors the speed of each wheel. If it detects that any wheel is about to lock up, it automatically reduces the braking force on that wheel, allowing it to continue rotating. This process helps maintain steering control and stability, as locked wheels can lead to skidding and loss of control.

The effectiveness of ABS is crucial for safety, particularly in adverse weather conditions where traction is compromised. It allows drivers to brake hard while still being able to steer, ultimately reducing the risk of accidents and enhancing overall vehicle control. Other systems, such as traction control and stability programs, serve different purposes related to vehicle stability and traction but do not directly prevent wheel lock-up during braking.
