ON THE HUNT FOR BRAKE DUST PARTICLES

INTERVIEW WITH PHILIPP NYHOF, DEVELOPMENT ENGINEER AT TMD FRICTION

With the new Euro 7 standard, nonexhaust particulate emissions come into focus for the first time. Accordingly, from January 2025 at the earliest, strict requirements will also apply for brake and tyre abrasion on all newly registered passenger cars. In November 2022, the European Commission presented a draft that stipulates that 7 mg of fine particles per kilometer may be emitted - i.e. for all four brakes together - and that for passenger cars and light commercial vehicles. As a Friction Expert TMD Friction is assist- ing with the preparation of the Euro 7 in the area of brake emissions and is working closely with vehicle manufacturers and other suppliers.

Euro 7 targets brake abrasion for the first time. How can the brake pad contributetosustainablemobility?

There’s no question ‒ fine particulate matter is created by mechanical abrasion in the braking process of a friction brake and is released into the environment, which can lead to breathing and cardiovascular disorders.

That’s why it’s not only safety, but also protection of the environment and human health which are the top priorities in TMD Friction’s development department. We make all of our friction material mixes ourselves and the raw materials used have to go through thorough checks. And that’s exactly what we do in our own laboratories in each development process. As a result, we make virtually all of our pads without copper or antimony, for example.
