The different systems of a vehicle allow it to move safely, among these systems one of great importance is the brake system. The braking system promotes the stopping of the vehicle in an efficient and safe way, for this to occur it is necessary to dimension it correctly, in order to avoid the occurrence of failures during its activation. During braking, the kinetic and potential energies of a vehicle are converted into thermal energy through the friction of the disc with the pad. The overheating of the discs can cause problems and lead them to fracture. Thus, this study aims to analyse the structural and heat dissipation capacity of the discs for a 250cc motorbike, ensuring that the brake does not fail during use.
