Brembo reduces brake dust emissions by 90 percent with new technology

In Italy, automotive manufacturer Brembo has developed an innovative brake and pad set named Greentell, aimed at drastically reducing brake dust emissions. This project began about a decade ago when the company identified the need for a solution that was feasible for mass-market applications rather than just specialty products. Greentell features a laser metal deposition coating, which is implemented on both brakes and pads, promising to cut emissions by 90 percent while enhancing durability over traditional braking systems. Furthermore, this marks a significant development within the automotive industry, where manufacturers are under increasing pressure to reduce overall vehicle emissions, including those generated from braking systems. As electric vehicles (EVs) gain popularity, there is a growing concern over the non-exhaust emissions produced by traditional brake systems, including particulate matter that contributes to air pollution. The Greentell brake system also caters to the performance car market, where brake wear is inevitable and such advancements can be particularly beneficial for maintaining cleanliness and functionality. Though the coating thickness applied is between 100-120 microns, which means the discs won't last indefinitely, they are expected to require less frequent replacements. Such advancements could help fulfill regulations like the Euro 7 standard in Europe, where stringent emission controls are enforced. Brembo acknowledges the technical challenges that arose during the development phase. They sought to strike a balance between high performance and environmental sustainability, which can often conflict in vehicle design. Greentell is described as the beneficial compromise between delivering impressive driving experiences for car enthusiasts while also adhering to eco-friendly practices. The anticipation of what this could mean for other regions, such as the U.S., underscores the transformative potential behind this innovation, especially in areas lacking rigorous emissions regulations. Users have expressed enthusiasm about the potential for less brake dust accumulation, which is known to be a disadvantage of conventional brakes. The laser metal deposition technology promises to reduce the undesired effects of conventional brake use while simultaneously addressing concerns regarding vehicle and driver health. Ultimately, Brembo positions Greentell as a pioneering product that responds to the dual necessity of performance and environmental responsibility in the modern automotive landscape.
