This paper presents complex eigenvalue analysis of commercial vehicle air disc brake system. To increase a reliability of a brake finite element model, the mode shapes and natural frequencies of the individual brake components are obtained by comparing form modal analysis and modal test. (The modal analysis and test shows that difference of the natural frequency is very small.) As a result of squeal analysis identified unstable modes of air disc brake system, a similar dynamo noise test. Additional, confirmed the final improvement model through parameter study that decrease the brake squeal.
