Static analysis methods have been applied to substantiate and develop several regressive models of kinetic characteristic of shoe and wheel brake using a variety of elastic loading forces as well as dissipative ones. It is demonstrated that changes in character and force intensity in brake system of kinematic chain factor into changes in brake friction coefficient in terms of value, brake application function, and motion speed. Correlation analysis supports close linear dependence of friction coefficient; regularities of optimum regression model simplification in the context of sampling amount decrease, observation dispersion increase, and adherence to specifications of identifiability have been indicated. The results make it possible to say that frictional coefficient of brake is of aggregate properties depending upon inertial behaviour, elastic behaviour, and dissipative behaviour of each kinematic pair of given tribological system; frictional vibrations synthesize all properties of braking system broadening friction control area in terms of brake device.
