In this study, the mathematical model for a brake system in a dynamometer is proposed to identify brake torque variation (BTV), and correlations between the dynamo test and simulation are determined. The interaction between the pads and the disc on the contact patch is simply modelled as a point-contact element and the transient response analysis in the time domain is introduced. The model indicates that the amount of BTV is linearly proportional to the pad stiffness, the friction coefficient, the disc thickness variation, and the effective radius of the brake pads. To verify the analytical model, a brake dynamometer is used and additional material tests are carried out. The dynamo test shows that the suggested model has reasonable accuracy in predicting the BTV of a brake system.
