What Happened
ZF has presented the world premiere of MAXX Uniper, its next-generation air disc brake for heavy-duty commercial vehicles, at IAA Transportation 2026 in Hanover, Germany. Built on ZF's single-piston brake technology, it is designed to meet today's performance and operational needs while supporting vehicle manufacturers in addressing upcoming EURO 7 brake-particle reduction requirements. In combination with a specially coated rotor, it reduces brake-particle emissions by up to 65 percent, while delivering consistently high performance even under demanding operating conditions.
up to 65%
Achieved in combination with a specially coated rotor, targeting EURO 7 brake-particle requirements.
- Compact, modular single-piston design with fewer parts, supporting high reliability and easier servicing
- Proven bi-directional adjuster regulates the running clearance between brake pad and rotor, supporting even pad wear and reducing the risk of overadjustment
- New carrier and brake pad system enables convenient brake pad replacement
- Modular architecture lets manufacturers apply one air disc brake concept across global heavy-duty commercial vehicle platforms and applications, reducing application and release efforts
- Optional plug-and-play continuous wear sensor is exchangeable and calibration-free, reducing maintenance effort and increasing vehicle uptime
- Robust sealing protects the brake against dirt and debris in demanding operating environments
“MAXX Uniper brings together what the commercial vehicle industry needs for the EURO 7 era: reduced brake-dust emissions, powerful braking performance and proven reliability. It demonstrates how ZF is translating evolving regulatory requirements into practical technology that creates value for vehicle manufacturers and fleets.”
MAXX Uniper builds on more than 30 years of ZF work in single-piston air disc brake technology and 12 million units sold, and represents the next generation of ZF's MAXX air disc brake platform. It delivers brake torque of up to 30,000 Nm for demanding heavy-duty commercial vehicles. The brake also strengthens ZF's ability to provide integrated axle systems for conventional, hybrid and fully electric commercial vehicles, part of a broader technology portfolio supporting manufacturers in meeting EURO 7 requirements. By combining the low brake dust particle emission technology with efficient and electrified chassis, driveline and further solutions, manufacturers can help lower the environmental impact of road transportation.
MAXX Uniper makes its world premiere at IAA Transportation 2026 in Hanover, Germany, where it is shown in Hall 21, Booth B42, through September 20, 2026
Start of production is expected
Previously from ZF
ZF's brake-dust work predates this launch: in September 2026, ZF Aftermarket unveiled TRW DTEC brake pads and discs that cut PM10 emissions by up to 80 percent in testing, aimed at helping independent repair shops prepare for Euro 7. ZF has also been promoting a technology-open mix of hybrid, electric and efficiency technologies to help commercial vehicles cut emissions at a pace each fleet can afford.

Why this matters
Brake dust is part of the upcoming EURO 7 brake-particle reduction requirements, so truck and bus manufacturers need brakes that cut particle emissions without giving up stopping performance. ZF says the modular design can be applied across global heavy-duty platforms, which matters for vehicle manufacturers and for fleet operators watching servicing effort and vehicle uptime.
Terms in This Story
- EURO 7
- A European emissions regulation; the source refers to its brake-particle reduction requirements for vehicle manufacturers.
- PM10
- Airborne particulate matter up to 10 micrometres in size; in this case particles released by braking rather than by the exhaust.
- air disc brake
- A heavy-vehicle braking system in which compressed air actuates a disc brake.
- single-piston
- A brake design that uses one piston to press the brake pad against the rotor.
