The Anti-lock Brake System (ABS) is most commonly found on newer vehicles for safety purposes. This system is designed to prevent the wheels from locking up during hard braking, which can lead to a loss of steering control. By allowing the wheels to continue rotating, ABS helps maintain traction and enables the driver to steer while braking. This is particularly important in emergency situations or on slippery surfaces, where control is crucial for preventing accidents.

As for the other options, traditional drum brakes, while still found in some vehicles, are becoming less common in favor of disc brakes, especially in performance and safety-oriented models. Vacuum brake boosters are used to enhance the braking force provided by the driver but do not inherently add safety features. Hydraulic brake systems are a critical component of modern braking systems but do not focus on safety enhancements like preventing wheel lock-up.
