Our analysis is focused on modeling of friction phenomena exhibited by a brake like duo-servo system. The occurred in girling duo-servo brake an frictional mechanism can be modeled approximately by two degrees-of-freedom mechanical system, where a normal force varies during displacement of a block. The Coulomb friction is used after numerical analysis, and a normal force pressing the sliding body to a belt depending on an angle bar motion of the analyzed system is applied. In addition, the numerical analysis is supported by investigation of the real laboratory object modeling the feedback reinforcement of friction forces acting on the block.
