Haldex - ModulT® Overview
Thrust Plate / Piston Design
ModulT® Robust One-Piece Integrated Thrust Plate / Piston Design
Assures even pad wear, and when combined with the proven brake adjuster mechanism supplies consistent, maximum brake output force throughout the life of the brake pads.
Peg to dimple interface.
Piston Thrust Plate and Pad Backing Plate Interface Design
Pegs on the thrust plate interface with dimples on the brake pad backing plate creating a stable connection for proper pad alignment and brake force vibration resistance.
Common inner and outer brake pad design also simplifies replacement.
Designed for Ease of Service
Fewer Components for Simplified Maintenance
The simplified design of the DBT22LT single piston caliper features fewer parts than twin piston calipers, making maintenance easier. Common inner and outer brake pad design simplifies replacement.
Wheels don’t need to be removed to visually check wear.
Dual Pad Wear Indicator Gauge Pins
The DBT22LT GEN II features two easy to access pad wear indicator pins. One located near the leading slide pin and a second pin near the trailing slide pin.
Competitive designs include only one indicator pin or require a complicated measuring process to determine pad wear.
Optimized weight saving single piston design.
The DBT22LT GEN II is brilliantly designed with features that simplify maintenance, lower operating cost and keep you on the road.
- Robust performance in an optimized, lightweight truck brake.
- Brake force supports up to 23,000 lb. gross axle weight rating.
- Equipped with HALDEX LifeSeal+ Spring Brake Actuators.
- Compatible with industry standard ConMet Pre-Set PlusTM hub and rotor assembly.

SAF P89 Air Disc Brakes
SAF 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 has developed a family of disc brake systems to meet the unique requirements of the North American trailer market.
SAF P89 Advantages
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.
Shorter Stopping Distances
When compared to drum brake systems.
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.

Designed for the North American Market
- 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.

SAF ULX40
Trailer Slider Suspension System
SAF ULX40 Features
Lightweight with Quality Ride Performance
The lightweight SAF ULX40 allows more payload while delivering the quality and handling control required without the complexity of air-ride.
Independent testing of road conditions and impact on cargo shows that, along with today’s improved packaging material and pallet configurations, the mechanical suspension system performs to the ride quality standards expected by North American on-highway fleets.
Additional ULX40 Features Include:
Slider Sub-Frame
Manufactured with 80KSI yield steel and strategically located crossmembers to resist racking and buckling. Models available to accommodate 1-3⁄8˝ and 1-5⁄8˝ pins.
SAF X-Series 5.75" Diameter Axle
The optimized design of the 5.75˝ axle brings a 20 lb. weight savings per tandem, and is over 30% more rigid when compared to the standard 5˝ diameter axle.
Qwik Release® Pin Pull
With 20% less pulling effort than competitive models, one person can easily reposition the slider - also eliminates bound-up pin problems.
