Air Disc Brakes for Tractors and Trailers

Maximum braking power, shorter stopping distances, and improved safety. Longer service intervals and faster maintenance that helps lower costs and downtime. It’s easy to see why air disc brakes continue to grow in popularity.

With more than 4 million on the road in North America – and more than 45 million globally – no one else can offer the same field-proven performance as Bendix. That's why nearly 75% of the North American air disc brake market trusts the Bendix® ADB22X® – the only air disc brake approved at all major truck and trailer OEMs.

Bendix® Air Disc Brake Pad Wear Sensing Technology

Want to take the guesswork out of brake pad replacement and lower your total cost of ownership? Pad wear sensing technology can help reduce maintenance costs because technicians will know when pads are nearing end of life without removing the tires. This allows fleets to proactively schedule maintenance and avoid damage to costly components – like the rotor. The system records a Diagnostic Trouble Code (DTC) for worn pad detection to signal when the pads are nearing the need for replacement.


  • Wired to dedicated wear sensing Electronic Control Unit (ECU), Anti-Lock Braking System (ABS), or OE control module
  • J1939 CAN messages broadcast by ECU is read by telematics unit or diagnostic equipment


  • Integrated with Bendix® TABS Premium and Advanced ABS
  • Power Line Carrier (PLC) message is read by telematics unit or diagnostic equipment
  • Fits most trailer types
