Euro 7: less brake dust

Euro car owners rejoice! Euro 7 standards coming into force in 2026 will regulate the amount of brake dust emissions.

Somewhat old news but still news to me. It will be interesting to see how this affects braking feel and performance that we love with high dusting brakes.

Also interesting that brake dust is mostly from rotor wear and not the pad itself.

Audi started playing with low dust adherent friction material about 6 years ago and ended up with brake judder they had no idea what to do with....lol, like the Asian and Domestic OEMs that have been dealing with it for years.

One can absolutely create the same amount of friction or better, but it comes with a different set of problems. There is no free lunch.

Don't Euros mostly use softer rotors?

Akebono's Euro pads are very good for stopping power and low dust.

From this table, it seems the limits are lower for electric than other cars, though an EV is probably harder on brakes

I've tried Akebono Euro pads and while they produce minimal dust, the feel and bite is incomparable to the Textars that I replaced them with. They are also not ECE R90 compliant as far as I know.

As for the lower limit on EVs, it is explained that they use more regenerative braking

Plenty of ceramic pads create dust. The fact that the dust is invisible and/or does not stick to the wheels does not mean it is nonexistent.

sounds like another backdoor EV mandate.
since they regenerate their dusting is less.

Makes me wonder how they will regulate tire particles since EV's produce considerably more.

Porsche Surface Coated Brakes to the rescue.

I had Akebono Euro for 3,000mls. Absolute junk performance wise.

I really don't get people being bent out of shape about dust but I clean my car only once a year.

It about "pollution". Same reason the state of Washington started the whole initiative to reduce copper in brake pads back 15 years ago or so, and then CA followed suit.

Typically, the domestic/asian vehicles utilize an adherent friction with a harder iron brake rotor, while the euros used a more abrasive friction material with a softer iron rotor. The ONLY way to reduce dust is to move towards a more adherent setup....which in the more corrosive areas of the world will cause lots of problems. Abrasive pads clean rotors very well...adherent pads do not.

thank you for that insight

That’s actually a lot more “emissions” than I’d have expected.
