Euro 7: Why brake discs need to communicate now
The Euro-7 standard is changing the rules of the game— including for brake systems!
(PresseBox) - From 29 November 2026, new limit values for particulate matter emissions from brake wear will apply. The challenge is to minimise particulate matter and ensure that the condition of the brake disc can be verified throughout the product life cycle.
Material change on the horizon
In the past, most brakes were made of grey cast iron or cast steel. In order to reduce particulate matter, they are now coated with a chrome or molybdenum alloy. However, in view of the new Euro 7 standard, ceramic brake discs are increasingly coming into focus. Carbon-ceramic brake discs, for example, are being used to reduce emissions in accordance with the new standard. This combination of materials emits up to 90% less particulate matter. Regardless of which variant the manufacturer chooses, however, the thickness of the coating must be regularly checked in accordance with the upcoming emissions directive to ensure that the required values are met. Until now, the technical approach to this has been extremely complex and costly.
The solution is laser-based wear marking
With this method, brake discs can be visually assessed at any time, without the need for sensors or removal. Trotec uses a 100-watt picosecond laser for this purpose, which employs cold ablation to create markings with a depth of 90 µm ± 5 µm without subjecting the material to thermal stress. The cycle time depends on the project and line. For example, it is 6 seconds for a 3 mm circle. The roughness (Rz) remains below 10 µm, guaranteeing high legibility even after thermal stress.
The key to meeting standards lies in the combination of material and marking technology
For example, a European sports car manufacturer uses Trotec lasers to mark wear indicators on carbon-ceramic discs. The marking remains legible even after exposure to 600 °C and enables easy visual inspection during maintenance.
"With our laser-based wear marking product solution, we enable not only OEMs and suppliers to comply with Euro 7, but also create real added value for their workshops and customers."
