When modernizing older generation vehicles, there is a need to modify the braking system to ensure its effectiveness in the new design configuration and for different technical characteristics of the vehicle. The article presents the results of analyses on improving the stability of a military special vehicle during braking. Analytical calculations used to optimize the distribution of braking forces to the vehicle axles are described, as well as the results of traction tests on the effectiveness of the service brake system as a function of the modifications performed.Military special vehicles are not subject to mandatory homologation tests, including braking system tests. During prototype testing for vehicle approval for service in the Polish Armed Forces, the effectiveness of the service brake system is checked in Type 0 and Type I tests. An important feature subject to assessment is also the stability of movement during braking. Special versions of military vehicles are built on chassis previously introduced into service. The installation of specialized equipment with large dimensions and mass leads to a significant increase in the height of the center of mass. This causes problems during intensive braking. The dynamic loads on individual axles increase, which creates difficulties in distributing braking forces to individual axles. (…)
