Particulate emissions from brakes will be taken into account from 2023

Even if the compulsory technical inspection of motorcycles has been abandoned in France, the government still has projects affecting our cars. In particular, from January 1, 2023, the brake particle emissions will be evaluated by experts. In the event of irregularities, a return visit can be arranged.

As you may know, compulsory technical inspection of motorcycles has been abolished in France, much to the relief of the irate motorcycle federation. Nevertheless, and only a few drivers know it, the technical control of our cars will be increased again from January 1st, 2023.

At that point, more screening criteria will be added to the long list that is already in place. In addition to measuring CO2 emissions from your vehicle’s exhaust, mechanics also need to Assess particle emissions from brake pads. In fact, when braking, the friction of the pads on the discs creates fine particles that are dangerous to health and the environment.

Particulate matter is also measured during the scrutineering

These include particles with a diameter of less than 10 μm and 2.5 μm, which originate from abrasion of the brakes, but also from the wear of tires and road surfaces. From now on, Particulate matter emissions from brake pads and tires are measured every two yearswheel by wheel. To this end, professionals in the sector are gradually being equipped with measuring devices capable of checking to the tenth of a micron.

The vehicle is installed on a rolling bench where continuous braking is performed at various speeds (between 160 and 0 km/h). Unfortunately and to the great displeasure of the mechanics the exact scope has not yet been determined by the French authorities. In other words, it is impossible to know at what threshold a return visit must be issued. There is also the problem of cars equipped with drum brakes, which have the particularity of trapping and accumulating particles inside. This makes accurate measurement impossible.

Unsurprisingly, professionals in the industry aren’t really welcoming of these new criteria. That’s what they particularly fearAt least every tenth car is subjected to a cross check because of excessive particle emissions. As a reminder, an OECD report published in December 2020 asserted that car tires and brakes will pollute more than exhaust fumes by 2035.
