Brake failure is a major safety concern in vehicles, particularly in two-wheelers, and can lead to accidents. To improve the safety of two-wheelers, this study proposes a new design for brake disc rotors with slots that can withstand the stresses and heat generated during the braking process. The performance of the rotor was analyzed using ANSYS 16 software through a combination of static structural analysis and transient thermal analysis. Static structural analysis was conducted by applying a braking force to a specific area while keeping the brake mount points fixed, and transient thermal analysis evaluated the effects of temperature changes on the brake system over time. The study considered various materials, including Grey cast iron, Ti6Al4V, and AISI 6150. Based on the analysis of von-mises stresses, shear stresses, strains, deformations, and total heat flux, AISI 6150 was identified as the best material for the brake disc rotors, as it can increase the performance of disc rotors and potentially reduce accidents. The findings of this study have practical implications for the design and manufacture of safer and more efficient brake systems in vehicles.
