Firstly, vehicle brake noise test and bench noise test are performed to measure brake caliper operation deflection shape (ODS); secondly, a finite element model of disc brake friction coupling is established. A complex eigenvalue of the brake system is calculated, and the trend of brake moan noise is predicated with the negative damping ratio of brake system dynamic model. Finally, the vehicle brake noise test result, brake caliper ODS as well as the unstable modal shapes are compared, which proves that the finite element model can forecast the brake moan noise effectively. And it is also indicated in the paper that the method combining vehicle test, bench test and finite element simulation is an effective method to control the brake moan noise.
