Air disc brakes (ADB) are now standard for many new trucks built after 2018 and can be ordered on either the steer or drive axles, or both. ADB can also be ordered for most trailer types. From a safety standpoint, ADB can help reduce the risk of rear-end crashes. According to Fleet Equipment Magazine, “The main strong point for disc brakes (over drum brakes) is reduced stopping distance. With disc brakes, that distance can be anywhere from 17% to 33% shorter than drum brakes, depending on speed.”
