AB Thermal problems of brake system of a heavy duty engine are analyzed in the article. The agricultural motor vehicle is able to travel at 40 kph speed and its weight is 30000 kg. Owing to friction of brake discs, significant amount of heat is released when brake of this vehicle of large weight is applied. For the brake to operate in a reliable way, it is essential to prevent overheating.Design of brake system is described in the article. Description of experiments conducted for inspecting heating and evaluation of results are also included in it. After that, the heat released during brake application is determined. It is also discussed when the brake is operating in a thermally safe way under various conditions of cooling down. The article shows at which temperature damage of cooling oil occurs. This essay means further development of the results described in work [11]. The analysis constitutes part of the project aiming at optimization of wheel body.
