To improve the efficiency of the operation of freight rolling stock at the present stage of development of the railway industry, it is important to introduce its modern designs. At the same time, special attention should be paid to the rolling stock brakes, as the most important structural unit in terms of traffic safety. According to studies of the technical condition of the brake equipment of freight wagons, it has been established that one of the most damaged units is brake pads. As a result of operating load conditions, they experience uneven wear of the working surface – wedge-dual wear. A study of the load of a composite brake pad of a freight wagon with wedge-dual wear has been carried out. It has been established that the presence of such wear causes an additional load on its structure, including thermal. In this regard, not only the pad destruction, but also a violation of the safety of train traffic can occur. The conducted studies will contribute to the creation of recommendations for managing the temperature effect on the brake pad, as well as improving the safety of train traffic and a significant reduction in operating costs.
