Working Principle
Structure feature:
Monoblock design of the caliper: Improved tightness due to higher stiffness of the caliper
Two guide pin design: Sliding smoothly, improved pad uneven worn out
Dual piston: Better caliper stiffness, larger reserve strove; Reduced risk of uneven pad wear
Synchronization chain: Compact design, reduced weight, better synchronization
Wear Adjuster ball ramp clutch: Well-defined adjustment function over brake life-time

Rim size: 17.5” or 19.5” or 22.5”
Brake Pad surface per pad: 116cm2 or 150cm2 or 196cm2 or 170cm2
Rotor outer diameter: 335mm or 377mm or 430mm

The advantage of the Air Disc Brake:
Stopping distance: Requirement for higher brake torque level, up to 30% stopping distance reduction resulting caused due to the usage of ADB on all wheels (truck & trailer)
Performance: Temperature fading, up to 75% increased brake torque compared to drum brakes at higher temperature levels; speed fading, up to 40% more brake torque at higher speed level when using ADB
Weight: Weight advantage compared to drum brakes on dedicated ADB axles, at the front axle -30kg, at the rear axle - 65kg
Comfort: Low self amplification of the ADB, Low hysteresis figures of approx. 10%; Low pulling behaviour on front axles as a result of low brake torque variation (R/L); Good brake response.
