In this paper, the optimal design process is introduced to avoid brake squeal noise generation for calliper housing design modification. The complex eigenvalue analysis method is employed to compute the instability characteristics, and the topology optimization design method and the response surface method are used as optimization tools. The design variables are set on the finger part of the calliper housing as the calliper housing part is good for various design modifications. In the brake noise problem, it is more effective to modify the shapes of various parts than to optimize one component shape. In particular, the mode characteristics of the carrier bracket and the mode couple characteristics between the disc rotor and the pad lining are considered as important proper ties. However, it is not appropriate to deal with the mode characteristics of various components simultaneously in building the systematic design process; hence, the design parameters are usually restricted to carrier shape modification for mode shifting or to pad design modification for mode decoupling such as slot cutting. In this research, it is shown that the dynamic instability of the brake system can be reduced by improvement in the design of the calliper housing according to the optimal design process. The magnitude of the dynamic instability is reduced by about 22 per cent compared with the original brake calliper model, and asymmetric finger shapes are obtained in the optimal calliper housing design. This research could be the basis of an asymmetric calliper design that would be a better choice for brake noise reduction.
