Otto Zimmermann welcomes the ongoing negotiations on the Euro 7 limits for brake dust and brake disc abrasion.
The specified values will apply from November 29, 2026, for newly type-approved passenger cars and light commercial vehicles, and from November 29, 2027, for all newly registered passenger cars.
At present, there are no specific requirements for the aftermarket (IAM) – neither regarding what is to be tested nor how proof of compliance with the limits should be provided.
"A final decision on the requirements for the aftermarket has not yet been made," emphasizes Otto Zimmermann. "We will continue to closely monitor this process and involve our partners in product development."
Technologies for minimizing abrasion
In order to meet the stricter particle limits, Zimmermann relies on modern / advanced coating and friction partner technologies:
- Carbide-coated brake discs: These highly wear-resistant coatings significantly reduce abrasion.
- Optimized friction mixtures: Special formulations reduce the proportion of fine particles during braking.
Additional technical measures
Closed braking systems such as drum brakes are also mentioned as a possible addition. Otto Zimmermann has been offering brake drums for the aftermarket in this sector for over six decades. The relatively closed system allows brake drums to better retain fine dust.
Statement from Otto Zimmermann
"We are aware of the importance of the Euro 7 standard and see it as a great opportunity for innovation," said a spokesperson for Otto Zimmermann. "That is why we are already developing our own solutions for brake discs in combination with specially developed brake pads during the ongoing negotiations. In-house test benches are available to ensure compliance with future limit values. These have recently been supplemented by a particle test bench sourced specifically for this purpose."
