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™ air disc brake system to meet the unique requirements of the North American trailer market.

Considerable Weight Savings

50 lbs. Per Tandem Savings when compared to drum brake systems.

Reduced Maintenance

  • 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.
  • Five-Year Parts and Labor Warranty.

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.

Designed for North America

  • SAF SBS 2220-K0 Dual Piston Caliper Design – Increases braking performance and pad life, uses larger brake pads and provides more even pad wear when compared to a single piston design.
  • Dual Sealed Slide Pins – Maintenance requirements simplified by eliminating the need for lubrication.
  • Premium Brake Chamber – All steel design with full immersion e-coating of housing and internal components for long life corrosion protection.
  • Semi-Metallic Disc Brake Pads – 20% larger to provide the optimum balance of stopping power and long wear life to extend service intervals.
  • Heavy-Duty Vented Rotor – large internal cooling channels and 30% more wearable rotor surface than comparable designs. More evenly dissipates heat to reduce rotor distortion for a long service life.
  • Heavy-Duty Parallel Spindle Wheel End – robust spindle design with large 89mm inner and outer wheel bearings for enhanced performance, reliability and unmatched durability.

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.
