What Are The Safety Advantages Of Using Air Disk Brakes

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.”

Other advantages of using ADB include:

  • No brake fade caused by heating up the brakes due to excessive usage.

  • Generally less maintenance, although not maintenance-free.

  • No slack-adjuster-related “out of adjustment” violations from roadside inspections.

  • Longer life before replacement.

  • Use of a caliper/pad mechanism, compared to the lining/drum/S-cam mechanism found on drum brakes.

Consider the type of operation you run before choosing the equipment to best fit your needs.
