The braking system is one of the most important vehicle systems, therefore, its optimised operation is essential in the dynamic performance of the automotive project; in addition to ensuring the necessary security of the object of study. Consecutively, the in-depth study on the sizing and performance of the braking system becomes necessary and, using software to assist in the manipulation of the parameters that influence this system, the automotive industry has presented different solutions in recent years, especially due to the use of central electronics such as the brake system module (BSM). In this context, the present work simulates, via a multibody virtual model and the aid of software such as VI-CarRealTime, the dynamic behaviour of a vehicle according to the braking system efficiency loss. With this goal, the virtual model is correlated with a physical test car and the conditions proposed in the AMuS test are executed, where the friction between the pad and the brake disc is changed. Using driver-in-the-loop simulation in a vehicle dynamics simulator with nine degrees of freedom, it was noted, qualitatively, that the loss of brake efficiency through g-force in each braking results in a long time for the vehicle to react according to the driver's assessment and by telemetry.
