ZF MAXX Uniper Air Disc Brake Targets EURO 7 Rules

ZF MAXX Uniper Air Disc Brake Targets EURO 7 Rules

ZF Friedrichshafen AG is presenting MAXX Uniper, its next-generation air disc brake for heavy-duty commercial vehicles, as a world premiere at IAA Transportation 2026. Production is expected to start in 2027. The single-piston system is designed to address upcoming EURO 7 brake-particle reduction requirements while supporting demanding commercial-vehicle applications. Its specially coated rotor can reduce PM10 emissions by up to 65%, while the brake delivers torque of up to 30,000 Nm. The system also combines a compact design with features intended to support reliability, servicing, and integration across global heavy-duty commercial-vehicle platforms.

Brake Design Targets Lower Particle Emissions

The MAXX Uniper uses a specially coated rotor designed to reduce particulate emissions generated during braking, with PM10 emissions reduced by up to 65%. The development is focused on upcoming EURO 7 requirements for brake-particle reduction, making emissions performance a central element of the system. The single-piston air disc brake can provide brake torque of up to 30,000 Nm, giving the system the braking capability required for heavy-duty commercial-vehicle applications. This combination of particle-emission reduction and high brake torque is intended to address both regulatory requirements and the operating demands of heavy-duty vehicles.

Bi-Directional Adjuster Supports Even Pad Wear

ZF has equipped MAXX Uniper with a bi-directional adjuster that regulates the running clearance between the brake pad and rotor. The mechanism is designed to support even pad wear while reducing the risk of overadjustment during operation. A new carrier and brake pad system also facilitates brake pad replacement, addressing servicing requirements for heavy-duty commercial vehicles. Together, these features are intended to make maintenance more straightforward while maintaining the required operating characteristics of the braking system. The compact architecture further supports reliability and integration across different global heavy-duty commercial-vehicle platforms and applications.

Service Features Support Demanding Operating Conditions

The system includes an optional plug-and-play continuous wear sensor that can be exchanged without calibration, simplifying replacement when monitoring hardware needs to be changed. MAXX Uniper also incorporates sealing intended to protect the brake against dirt and debris in demanding operating environments. These features complement the mechanical design by addressing maintenance and durability considerations alongside braking performance. The combination of service-oriented components, environmental protection, and a compact configuration gives ZF Friedrichshafen AG a braking system designed for heavy-duty commercial vehicles where reliability and straightforward servicing are important requirements.

IAA Transportation 2026 World Premiere

The world premiere at IAA Transportation 2026 places the MAXX Uniper development in the context of the next generation of heavy-duty commercial-vehicle braking systems. ZF Friedrichshafen AG has positioned the single-piston air disc brake around lower brake-particle emissions, high torque capability, serviceability, and compatibility with global vehicle platforms. With production expected to start in 2027, the development also establishes a future production timeline for the system. The emphasis on EURO 7 brake-particle requirements indicates that regulatory compliance is a key consideration in the brake's development and intended commercial-vehicle applications.

Industry Impact & Outlook

MAXX Uniper highlights how heavy-duty commercial-vehicle braking systems are being developed around both regulatory emissions requirements and practical fleet-service needs. Its stated PM10 reduction capability, high brake torque, wear-management system, replaceable sensor, and protective sealing combine environmental and operational considerations within one brake architecture. For vehicle manufacturers and braking-system users, the significance will depend on how upcoming EURO 7 requirements translate into application-specific engineering and production needs. The planned 2027 production start gives ZF Friedrichshafen AG a defined timeline for bringing the technology into heavy-duty commercial-vehicle applications.
