Brembo Greentell Brake System

Addressing Brake Dust in Modern Vehicles

Braking systems are essential for vehicle safety, but they also generate small particles during operation. When brake pads press against the brake disc, friction produces fine particulate matter known as brake dust. These particles can spread into the surrounding air and settle on nearby surfaces such as wheels and roads.

As vehicle emission regulations evolve, attention is expanding beyond exhaust gases to include other sources of pollution. Brake dust is increasingly recognized as a contributor to non-exhaust emissions in urban environments. This issue is particularly relevant as electric vehicles become more common, since they produce no tailpipe emissions but still generate particles from braking and tire wear.

The Brembo Greentell brake system was developed to address this emerging environmental challenge while preserving the safety and performance expected from modern braking technology.

How the Greentell System Works

The Greentell system combines specially engineered brake discs with optimized brake pads to reduce the amount of particulate matter produced during braking. The innovation focuses on improving the interaction between the disc surface and the pad material.

Brembo developed a surface treatment process for the brake disc that helps limit wear during repeated braking cycles. By reducing the rate at which the disc and pads wear down, the system can significantly decrease the release of particles into the environment.

Key elements of the Greentell system include:

• Specially treated brake discs designed to reduce wear
• Brake pad materials optimized for lower particle generation
• Reduced brake dust emissions compared with conventional systems
• Compatibility with modern passenger vehicles
• Long-term durability through improved surface protection

These features allow the system to maintain braking efficiency while reducing environmental impact.

Reducing Non-Exhaust Emissions

Non-exhaust emissions are becoming a growing focus in transportation sustainability. While vehicle engines have become cleaner over time, particles generated from braking, tire wear, and road abrasion remain significant sources of pollution.

Brake dust particles are extremely small and can become airborne, contributing to urban particulate matter levels. Technologies that reduce these emissions may help improve air quality, particularly in dense city environments where traffic levels are high.

The Greentell brake system represents one approach to reducing these emissions at the component level by modifying materials and surface properties rather than changing vehicle operation.

Braking Innovation for Future Mobility

Automotive manufacturers are increasingly exploring ways to reduce environmental impact without compromising vehicle safety. Braking systems must still provide consistent stopping power under demanding conditions while also adapting to new sustainability expectations.

Advances in materials science, surface engineering, and component design allow manufacturers to refine braking technology for both performance and environmental considerations. Brembo’s Greentell system reflects this trend by focusing on reducing particulate emissions while maintaining reliable braking performance.
