The Problem of Brake Wear and Environmental Pollution with Particles Obtained by Brake Wear - a New/Old Source of Pollution?

Abstract

The problem of brake wear has not been analyzed to such an extent from the point of view of ecology. One of the systems on the vehicle that emit particles, which often contain substances harmful to the environment and human life, is the braking system. Particles in this case are formed as a result of wear of friction pairs (brake pads and discs) due to vehicle braking. Analysis and research of the formation of particles of different sizes (PM10 and PM2.5) due to brake wear is very relevant today, so different systems and regulations are being developed that are related to this topic. By researching the influence of various factors on the resulting particle emission, as well as the mechanism of particle release, the answer can be found as to how much and what influences the resulting particle concentration. Thus, it is possible to develop new systems on the vehicle that would collect particles or optimize braking, development of new materials for friction materials, development of technologies for the production and processing of friction pairs, introduction of new legal regulations in the field of motor vehicles and the environment.
