Euro 7: Brake Discs Get Smart
Euro 7 mandates stricter brake emission rules from November 2026.
The Euro 7 standard, effective from November 29, 2026, introduces stringent regulations to curb particulate matter emissions from brake wear, pushing the automotive industry to innovate. This new directive not only targets reduced emissions but also mandates continuous monitoring of brake disc conditions throughout their lifecycle. As a result, brake systems are evolving, with advanced materials and laser-based technologies leading the charge to meet these rigorous standards.
Key Highlights
· Euro 7 Compliance: New limits on brake wear particulate matter emissions start November 29, 2026.
· Material Shift: Carbon-ceramic brake discs reduce emissions by up to 90% compared to traditional materials.
· Visual Inspection: Laser markings remain legible even after exposure to 600°C, simplifying maintenance.
Revolutionizing Brake Materials
Traditional brake discs, typically made from grey cast iron or cast steel, are being reengineered to meet Euro 7’s emission requirements. Manufacturers are now coating these discs with chrome or molybdenum alloys to reduce particulate matter. However, carbon-ceramic brake discs are gaining traction for their ability to cut emissions by up to 90%. These advanced materials require regular coating thickness checks to ensure compliance, a process that has historically been complex and costly. The Euro 7 standard emphasizes not just emission reduction but also the ability to verify brake disc condition over time, driving the need for innovative solutions.
