Brakes are one of the most important safety systems in a car. During the braking process, the brake disc is subjected to high stress, which causes cracks in the surface and overheating of the brake fluid, seals, and other components. The aim of this study is to find the brake disc design that provides the best results by performing thermal analysis of the vehicle's brake disc. This study was carried out in the ANSYS program. In this way, the temperature distribution in the brake disc of a moving vehicle was analyzed. In this study, two different materials (Aluminum Alloy, Grey Cast Iron) and four different hole diameter geometries (3 mm disc, 7 mm disc, 11 mm disc, and 3-7-11 mm disc) were used. In the comparison of materials, it was seen that the material with the lowest temperature was grey cast iron. When the geometries were compared, it was determined that the geometry with the lowest temperature was the 11 mm hole diameter disc design. These results show that a temperature of 333.94 °C was reached with cast iron material and 11 mm hole diameter disc geometry. When the heat dissipation of the vehicle's brake disc was examined, it was determined that the material with the highest heat dissipation was aluminum alloy. When comparing geometries, the 3-7-11 mm hole diameter disc achieved the best result. For this reason, the design with aluminum alloy material and 3-7-11 mm hole diameter disc geometry with a value of 0.26649 W/m2 was chosen as the best design in terms of heat flux.
