This work introduces one of simple method used to compare the results obtained from stand-test and road-tests of brake systems of automobiles, through the settlement factors for their relation to each other. The factors involve distribution of brake force between front and rare wheel axis, weight of automobile on front and rear axis during the brake process, force coefficients with servo-brake, moment of inertia on front and rear axles and brake way of a forward wheel of the automobile on the stand. To analysis of these importance factors, it is necessary to establish the correlations and factors influencing on the impact of diagnostic parameters. Mathematical formulations are performed to investigate the influence of these factors on both stand and road tests of automobile. The results showed that the brake way force decreases as the coefficient of force between the front and rear axles and basic surface increase while, it increases as the initial mass of automobile increases. Also the results show that the deceleration of the automobile increases as basic surface increases while; it decreases as initial mass of automobile increases.
