Bendix® ADB22X® Air Disc Brakes for Tractor and Trailer

Lower your TCO (total cost of ownership) and boost safety.

Maximum braking power, shorter stopping distances and improved safety. Longer service intervals and faster maintenance that help 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.

ADB Pad Wear Sensing Technology

The latest enhancement to our family of ADBs, Pad Wear Sensing Technology enables customers to know when their pads are nearing end of life conditions – without taking off the wheels and before any damage occurs to the rotor from worn pads. This technology is available on ADB22X air disc brakes for tractors and trailers. Find out more here.

Bendix® ADB Pad Wear Sensing Technology

Want to take the guesswork out of pad replacement and lower your TCO? Pad wear sensing technology can helps 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 pads are close to nearing replacement.

Tractor

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

Trailer

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

Rotors

Bendix offers Lightweight Splined® Disc flat rotor options for all ADB22X® calipers. The semi floating rotor improves heat dissipation and prevents heat cracking.

Bendix friction couple

The Bendix pad & rotor are designed specifically for each other, to extend the service life of both components

Use of non-Bendix pads can lead to costly rotor damage – because they are not designed with the rotor in mind

Rotors damaged by inferior pads may crack, leading to:

Out of service conditions: due to length, width, depth of cracking or crack over edge
Failed rotor: $2,000 replacement

ADB Replacement Pads

Choose the pad that’s right for your application and budget. Bendix® pad kits include OEM hardware, with B-Level copper compliant friction (through 2024) that maintains your 5-year caliper warranty.
