abstract This article presents the conditions and factors influencing the performance and requirements of brake disc materials. The wear resistance of brake discs must be as high as possible since the reliability of brakes is a fundamental factor affecting the safety of the object in motion. The influence of temperature on the materials was also analyzed, and materials were selected for brake disc components. This article is a research and review study. The article describes studies performed on a flat single disc brake. The authors presented the abrasive wear rate for the tested composites (AlSi12/carbon and AlSi12/aluminosilicates) before and after heat treatment (solution heat treatment at 520°C/4 h and aging at 220°C/4 h). Abrasive wear resistance tests were carried out using a TRN S/N 18-324 device from CSM Instruments, combined with the TriboX v.2.96 system according to the description from the US in the ASTM G 99-90 standard.
