The OEM’s Guide to Euro 7 – Laser Wear Marking for Brake Discs
Starting November 29, 2026, things get serious: The Euro 7 standard not only introduces stricter emission limits but also targets brake and tire wear. Particularly affected: braking systems – regardless of the drive type. But how can wear be efficiently and compliantly detected? The answer: precise, laser-based wear marking – ready for series production, cost-efficient, and Euro 7-compliant.

How can laser wear marks simplify brake disc monitoring for Euro 7 compliance?
The Euro 7 standard requires not only the reduction of fine dust emissions but also their detectability during operation. Workshops and vehicle owners need a simple, visual method to assess the condition of brake discs. This is where wear marking comes in: a precise, laser-based mark on the braking surface that makes the wear level visible – without disassembly or complex measuring technology.
Technical implementation: Laser precision for series production
| Category | Details |
|---|---|
| Task | Wear marking on the braking surface |
| Goal | Visual inspection for standard deviation and wear without disassembly |
| Technology | Trotec 100-watt picosecond laser |
| Product Features | |
| Solution status | Production-ready, already in OEM use |
| Process type | Cold ablation – minimal to no thermal load |
| Precision | Very high (±5 µm depth, Rz < 10 µm) |
| Cycle time | ~6 seconds for a 3 mm circle at 90 µm depth |
| Material suitability | Ideal for sensitive materials and series production |
| Geometry | Freely definable geometric shapes |
| Process stability | Stable process with clearly defined measurement strategy |
Carbon ceramic brake discs with a laser-etched wear marks: A promising path to Euro 7 compliance
| Criterion | Cast Iron | Carbon-Ceramic |
|---|---|---|
| Fine dust (PM10) | High (7–11 mg/km) | Low (0.5–2 mg/km) |
| Wear amount | High | Very low |
| Particle toxicity | High (metals) | Low (SiC, C) |
| Euro 7 compliance | No | Yes (potentially) |
Thanks to their high thermal stability (>600 °C) and low abrasion, CCBs produce 80–90% less fine dust than conventional brake discs – a decisive advantage for meeting the new limits.

Conclusion: Marking technology as an enabler for Euro 7
From November 29, 2026, the Euro 7 standard will fundamentally change automotive manufacturing, extending its reach beyond tailpipe emissions to also rigorously target brake and tire wear. This new regulation necessitates a paradigm shift in how brake system wear is detected and managed, demanding efficient and compliant solutions for all vehicle types. The answer lies in precise, laser-based wear marking, a technology already poised for series production. This innovative approach provides a cost-efficient, Euro 7-compliant method for visually assessing brake disc wear without requiring disassembly or complex measurement tools, marking a critical step towards future-proof vehicle production.
The combination of precise wear marking and low-emission brake disc materials like carbon-ceramic represents a future-proof solution. Trotec’s laser systems enable easy integration into existing production lines – without extensive R&D or long ramp-up times.
