Funded by the European Commission’s LIFE Programme, RE-BREATH – Reduction Brake Wear Emission in Transport Sector project, aimed to better understand and reduce non-exhaust particulate emissions from braking systems in urban fleets.
At the heart of the project is Brembo’s innovative braking system specially developed for heavy-duty vehicles, aligning with the upcoming Euro 7 standards. The system includes brake discs made from low-wear cast iron and copper-free brake pads specially designed to work in synergy with the new discs. The new pad will be available on the market by the end of 2025.
Brembo's contribution to the project, co-funded by the European Commission under the LIFE Programme, was validated by real-world testing across two cities: Bergamo (Italy) and Bratislava, identified as the urban centers with the highest PM1O concentration.
The results of the RE-BREATH project attested:
- significant increase in the service life of brake discs during road demonstration compared to historical data: +50% compared to OE (Original Equipment) systems and +100% compared to AM (Aftermarket) systems.
- PM10 emission reduction: -10% by comparing the OE (Original Equipment) system with the RE-BREATH solution, using the bench test emission factor and the EEA (European Environment Agency) methodology for emission estimation.
- A decrease in PM10 concentration between 40% and 70% at bus stops equipped with green barriers, confirming the effectiveness of environmental mitigation interventions.
The project's data were shared with Task Force 5 (PMP group, UNECE), a group focused on the measurement of brake wear particles from heavy-duty vehicles, to help develop future emission standards. The results also demonstrated the potential scalability of the system in other high-demand contexts, paving the way for wider adoption of sustainable components within fleets.
