The Euro 7 standard requires a reduction in brake wear, which entails verifiable wear throughout the product's life cycle. Workshops must therefore be able to assess the condition of the brake disc. The current approach is too complex and expensive, so OEMs and suppliers are looking for alternatives suitable for everyday use.
The focus is increasingly on coated grey cast iron or even ceramic brake discs. PM10 particulate emissions are up to 90% lower with carbon-ceramic brake discs than with grey cast iron, and wear and particle toxicity are also very low. In addition, coated brake discs can be laser-marked at different depths, providing a practical solution for compliance with the Euro 7 standard.
Visible, easy to maintain and cost-efficient
Trotec offers an integration laser for this application, producing markings with a depth of 90 µm ± 5 µm. Engraving takes less than six seconds, with a roughness below 10 µm providing a clear visual inspection and a simple way of checking the condition.
There is no need for time-consuming dismantling or sensor technology.
Application example:
A sports car manufacturer uses Trotec lasers to mark wear indicators on carbon-ceramic discs. The marking remains legible even after exposure to high temperatures, enabling simple visual inspection during maintenance. Customer quote: "The laser-engraved wear marking is a real game changer for us — it meets the standard while saving costs and reducing complexity."
