Ride with the Superior
Braking Performance of
SAF Air Disc Brakes

SAF -HOLLAND is recognized as a global leader in air disc brake technology, with millions of disc brake axles in service, worldwide, since 1996.

Leveraging its global network of engineering, testing and manufacturing expertise, SAF-HOLLAND has developed the P89 Plus™ air disc brake system to meet the unique requirements of the North American trailer market.

Featuring Haldex
Calipers and Actuators

Enhanced Safety is Reason Enough.

Fleets recognize the safety advantages of air disc brakes and are making it their number one priority as evidenced in a recent truck safety survey.

SAF P89 disc brakes will assure the stopping performance you expect, after all SAF is the global leader in trailer air disc brakes.


The advanced rotor and hub design features a proprietary bi-metallic casting process that mechanically joins two materials with unique properties into one assembly.

To redirect and control high temperatures associated with vehicle braking, the rotor is designed with a series of ventilation channels.

Unlike traditional rotors that experience extreme lateral deformation under high temperatures (umbrella effect), the P89 Plus™ rotor expands in a radial direction maintaining a flat and stable braking surface.

As a result, harmful stress cracks, and premature brake pad failures are significantly reduced.

Reduced Maintenance with P89 Plus™ Disc Brakes

  • Significantly Longer Brake Pad Life for Extended Service Intervals – Some fleets have reported a substantial increase in miles between brake jobs.
  • Replacing Disc Brake Pads Takes Less Than Half the Time – When compared to replacing conventional drum brake linings.
  • The Automatic Brake Adjustment Mechanism – Built into the disc brake caliper. This means there are no slack adjusters to maintain and brake stroke to control.
  • Lower Risk for Out-of-Service Adjustment Violations – When compared to drum brakes.
  • Designed to Accept Industry Standard Wear Parts.
  • Seven-Year Parts and Labor Warranty.

P89 Plus™ Long Life Sealed Bearings

Long lasting, leak resistance that protects against extreme temperatures and corrosive chemicals.

Braking Performance

Reduced Brake Fade – Traditional brake drums expand away from the brake lining during hard braking, resulting in brake fade. Disc brake rotors expand toward the brake pads during similar braking events, essentially eliminating mechanical brake fade and shortening the stopping distances compared to drum brake systems.

Tire Pilot Plus™

Improve Profitability by Enhancing Tire Life, Fuel Efficiency and Uptime

Optional Tire Pilot Plus™ not only controls pressure through inflation, but also maintains equal pressure across all wheels and features high pressure relief for overinflated tires.

The robust design sets it apart from competitive designs with durable components.

Proper Air Pressure is Critical to Tire Life

Full Contact
Optimizes traction, handling and maximizes tire life.

Outside Contact
Accelerates irregular tread wear, increases rolling resistance, and reduces fuel efficiency by up to 2%.

Center Contact
Only reduces tire life and traction. Tire is susceptible to tread damage and punctures.
