Euro 7: ZF also tackles brake dust

At IAA Transportation, ZF presented MAXX Uniper, a new pneumatic disc brake designed for heavy-duty vehicles. Combined with a disc featuring a specific coating, it could reduce PM10 particle emissions related to braking by up to 65%.

After the engine, the brakes

With Euro 7, the fight against pollutant emissions no longer stops at the exhaust outlet. Particles produced by brake wear are also covered by the regulations. Diesel or electric, a truck always needs to stop — and its brakes wear out.

The method imposed by Brussels can be debated. One thing is certain: manufacturers have to find solutions. And every additional technology raises the same question for hauliers: how much will tomorrow’s truck cost?

Up to 65% fewer PM10 particles

At the ZF stand, the answer is called MAXX Uniper. This new-generation pneumatic disc brake retains the single-piston principle that the equipment manufacturer has been using for more than thirty years. It can deliver up to 30,000 Nm of braking torque, enough to meet the requirements of heavy industrial vehicles.

The figure that attracts attention concerns particles: combined with a specially coated disc, MAXX Uniper could reduce PM10 emissions from braking by up to 65%, according to ZF. The clarification is important: this result does not concern the brake alone, but the complete system formed with this disc.

And in the workshop?

ZF also highlights a compact design, with fewer components, and simplified brake pad replacement. A continuous wear sensor will be available as an option. It can be replaced without calibration, which should make maintenance monitoring easier and limit downtime. Production is scheduled to start in 2027.

On paper, this is interesting: fewer particles, high braking power and maintenance designed with operations in mind. It remains to be seen what the system, discs and brake pads will cost, as well as their actual service life on the road. Because an innovation only makes sense for a haulier if it also delivers on its promises in the workshop and in the accounts.

Euro 7 is pushing engineers to look for answers even in components that received less attention yesterday. MAXX Uniper is a good example of this. But if every new requirement adds technology, we will also need to keep a close eye on what it adds to the final price of the truck.
