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.
