“…GCI discs are popular due to their advantages but, at the same time, are associated with high wear. In general, in GCI with ECE high-emitting brakes, the disc contributes around 60% to total mass loss [16,77,82,83]. With drum brakes, the contribution is lower; one study found 37% [83].…”

Particulate Matter (PM) air pollution has been linked to major adverse health effects. Road transport still contributes significantly to ambient PM concentrations, but mainly due to the non-exhaust emissions from vehicles. For the first time worldwide, limits for non-exhaust emissions have been proposed by the European Union for the upcoming Euro 7 step. For these reasons, interest in brake emissions has increased in the past few years. Realistic emission factors are necessary to accurately calculate the contribution of brake emissions to air pollution but also to estimate the emissions reduction potential of new or existing technologies and improved brake formulations. This paper reviews emission factors from light-duty vehicles reported in the literature, with a focus on those that followed the recently introduced Global Technical Regulation (GTR 24) methodology on brakes in light-duty vehicles. Reduction efficiencies of non-asbestos organic (NAO) pads, brake dust filters, ceramic discs, coated discs, and regenerative braking are also discussed. Finally, the emission factors are compared with roadside measurements of brake emissions and emission inventories worldwide. The findings of this study can be used as an input in emission inventories to estimate the contribution of brakes to air pollution.

The article is a multi-directional review of the current knowledge in the field of particulate matter emissions from motor vehicles, but not related to the combustion process in piston combustion engines. A summary of the research results available in the literature was provided regarding the size and composition of particulate emissions from abrasive wear of working elements of brake systems and tires. The mechanisms of particulate matter formation related to the wear processes of brake pads, discs and tires were described. Reference was made to currently available research results regarding the harmful, toxicological impact on health of chemical components contained in particulate matter, in particular on diseases of the respiratory and cardiovascular systems. A critical analysis of various, previously unstandardized measurement and assessment methods for the emissions of this particulate matter category was carried out, pointing to future needs. Relating, in particular, to the requirements of the new Euro 7 standard.
