Automotive brake noise has been a major concern in automotive industry and structural modification is a practical and effective way to reduce it. Here, a new method to estimate the critical friction coefficient is summarised, and then a sensitivity analysis is developed. The key is a reduced-order characteristic equation for computing the elastically coupled system's eigenvalues and their derivatives. Based on this reduced-order equation, a sensitivity analysis of the steady-sliding stability with respect to lining stiffness and lining geometry is presented for a drum brake system. This analysis eliminates need for new system models or a full complex eigenvalue analysis.
