ZF has unveiled its next-generation MAXX Uniper air disc brake for heavy-duty commercial vehicles at IAA Transportation 2026 in Hanover, Germany. The new brake system is designed to support compliance with upcoming EURO 7 brake-particle emission requirements, combining reduced brake dust emissions with high braking performance and a compact modular architecture.
When paired with a specially coated rotor, MAXX Uniper can reduce PM10 brake-particle emissions by up to 65%, according to ZF. The technology is aimed at helping commercial vehicle manufacturers address increasingly stringent requirements for non-exhaust emissions while maintaining braking performance under demanding operating conditions.
The MAXX Uniper builds on more than 30 years of ZF’s single-piston air disc brake technology, with more than 12 million units sold. As the next generation of ZF’s MAXX air disc brake platform, the system delivers braking torque of up to 30,000 Nm, making it suitable for demanding heavy-duty commercial vehicle applications.
A proven bi-directional adjuster regulates the running clearance between the brake pad and rotor. Tested under demanding environmental conditions, the mechanism is designed to support uniform pad wear and reduce the risk of overadjustment.
ZF has also focused on simplifying maintenance and integration. The compact brake design uses fewer components, supporting reliability and easier servicing. A new carrier and brake pad system enables convenient brake pad replacement, while the modular architecture allows vehicle manufacturers to use a common air disc brake concept across global heavy-duty vehicle platforms and applications.
For fleet operators, MAXX Uniper offers the option of a plug-and-play continuous wear sensor. The exchangeable, calibration-free sensor is designed to reduce maintenance requirements and support higher vehicle uptime. Robust sealing further protects the brake system from 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,” said Pawel Porczynski, Head of Business Unit Chassis Solutions, CVS Division, ZF. He added that the system demonstrates ZF’s approach to addressing evolving regulatory requirements through technologies designed to deliver practical benefits for vehicle manufacturers and fleets.
Start of production is expected in 2027.
MAXX Uniper forms part of ZF’s broader technology portfolio for supporting EURO 7 requirements. The company says the brake technology also strengthens its ability to provide integrated axle systems for conventional, hybrid and fully electric commercial vehicles. By combining low brake-particle emission technology with electrified and efficient chassis, driveline and other vehicle systems, ZF aims to help manufacturers reduce the environmental impact of road transportation.
