Brembo's New Brakes Cut Particulate Emissions By 90 Percent

![]() Brembo investigated a range of solutions before settling on using laser metal deposition. Physical vapor deposition, as used as a durability coating for wristwatches and firearms, was ruled out due to cost. 'So it can be used for some special application or some small pieces, but when you are speaking about 20 kilos of cast iron, PVD is not the right solution. LMD is a technology that [has been] available... [for] years, but [it hasn't yet been] applicable in a high volume application. So the goal is to find the best compromise between performance and process,' [Fabiano Carminati, VP of disc technical development at Brembo] told me. Together with the reduction in brake dust, there's an 80 percent reduction in surface corrosion compared to conventional brakes, but they won't last forever. 'The thickness of the layer that we apply is not so high -- we apply just 100-120 microns. That means that the disk is not a lifetime disk,' he said. That said, Greentell brakes should need replacing less often, and while that's not entirely in Brembo's best financial interests, neither is not being able to offer its customers a Euro 7-compliant product.
