For achieving the desired vehicle speed, the IC engine is very important, while for further vehicle speed maintaining and adaptation to road conditions, the braking system is important. With each brake's activation, wear products are forming, which are very harmful to the environment, because they can contain heavy metals. The braking working parameters (initial speed and braking pressure) are beside the achieved temperature in contact par, the most responsible, for particle formation and their release into the air. The particles forming can be divided by size on coarse, fine, and ultrafine particles, and which were observed in the paper. However, the greatest accent was placed on coarse and fine particles. For the determination of the composition of wear products, most often, laboratory tests were used. Particle composition greatly depends on the composition of brake pads, which can consist of about 30 components, and where some of these components have very unfavourable effects on people's health. So today, many researches are focused on finding such composition for brake pads, which will wear as less as possible, without disturbing the basic tribological properties. The conclusion of this paper shows that the applied materials for manufacturing the braking system are very important, as well as the construction, for the reduction of particle emission.
为了达到所需的车速，内燃机是非常重要的，而对于进一步的车速维持和适应路况，制动系统是重要的。每次刹车的启动，都会形成磨损产物，这些产物对环境非常有害，因为它们可能含有重金属。制动工作参数（初始速度和制动压力）除了接触副中的达到的温度外，对颗粒的形成及其释放到空气中也负有最大责任。形成的颗粒可以根据大小分为粗颗粒、细颗粒和超细颗粒，并在本文中进行了观察。然而，最大的重点放在粗颗粒和细颗粒上。为了确定磨损产物的成分，通常使用实验室测试。颗粒成分在很大程度上取决于刹车片的成分，刹车片可能由大约 30 个成分组成，其中一些成分对人们的健康有非常不利的影响。因此，今天，许多研究都集中在寻找这种刹车片的组成，它将尽可能少地磨损，而不干扰基本的摩擦学性能。本文的结论表明，制造制动系统的应用材料非常重要，以及结构，对于减少颗粒排放也是非常重要的。
