The braking system is one of the important systems from the aspect of vehicle safety, but it is also one of the systems that has a significant impact on the environment. Brakes are considered to be a source of non-exhaust particles, that is sources that create particles by the wear of the elements that are in contact with each other, and in this case, the brake friction elements (brake pads and rotating disc). Such particles often contain heavy metals that are part of the friction elements. There are a number of influencing factors that can affect the wear of the friction elements and increase the concentration of the formed particles. Laboratory methods of testing wear and particle formation, road tests and various simulations of brake wear are most often used for testing. In this paper, a review of methodologies for testing the formation of particles from the braking system, the materials used in the composition of the friction elements of the brake, as well as factors affecting the wear rate and concentration of particles of different sizes, based on the conclusions of other authors is presented. Based on this review, it can be concluded which quantities and factors need special attention during further research in the mechanism of formation of non-exhaust particles whose source is the vehicle braking system.

从车辆安全性的角度来看，制动系统是重要的系统之一，但是它也是对环境具有重大影响的系统之一。制动器被认为是非排气颗粒的来源，即通过相互接触的元件（在这种情况下，是制动摩擦元件（制动片和转盘））的磨损而产生颗粒的来源。这样的颗粒通常包含重金属，该重金属是摩擦元件的一部分。有许多影响因素可以影响摩擦元件的磨损并增加所形成颗粒的浓度。测试磨损和颗粒形成的实验室方法，道路测试和各种制动磨损模拟方法最常用于测试。在本文中，根据以下结论对制动系统中颗粒形成的方法，制动器摩擦元件组成中使用的材料以及影响不同尺寸的颗粒的磨损率和浓度的因素进行了综述介绍其他作者。根据此综述，可以得出结论，在进一步研究以车辆制动系统为源的非排气颗粒形成机理的过程中，需要特别注意哪些数量和因素。
