The paper presents the calculation of brake mechanism which involves determining the forces needed to be applied by the drive to reach the required braking moments at the wheel. The importance of braking system characteristics derived from how to active handle the vehicle and affect, in a decisive measure, valuing the performance of vehicle velocity and acceleration. Also, to assess the performance of braking mechanism, they aim to define the coefficient of efficiency and determining effectiveness characteristic depending on the thermal regime of work. Heating influences the dynamic performance of the vehicle brakes safely. To identify the evolution of brake heating they have become the realization of a measurement chain that was used for the measurement of all parameters during a long braking period. In the conclusions presented they show temperatures measured and how they could affect the determination of wear regime in operation.
