Summary
The subject is focused on the materials used for friction brakes of passenger cars, especially on their composition, properties and methods of testing their friction wear parameters. Another content of the subject is the behavior of brake system materials under different operating conditions, as well as the environmental aspects of friction processes during automotive braking, including an outline of the nature of these emissions and their measurement methods. The subject also includes the development of new brake materials and the legislative framework for the control and regulation of emissions from non-combustion processes in transport.

2. Brake materials - their groups, definition of the basic components of brake materials, their functions and production.
3. Automotive braking – braking mechanism, changes in brake materials, friction layer and its effect on braking efficiency. The formation of wear particles and their influence on the service life of individual components of a brake system.
4. Testing methods of the friction-wear properties of materials for automotive brake systems - laboratory and field tests. Arrangement of tests, standard test procedures, examples of obtained data and their interpretation.
5. Behavior of brake materials under different operating conditions – high brake temperatures, air humidity, de-icing salt solutions, etc.
6. Emission of solid particles - mechanism of formation, nature, methods of measurement and characterization of the chemical composition and morphology of wear particles.
7. Emission of gaseous particles - mechanism of formation, methods of measurement and characterization.
8. Legislative framework of emissions from non-combustion processes in transport - prepared legislation for the control and regulation of particle emissions.
