Minimizing brake squeal is one of the most important issues in the development of high performance braking systems. Recent advances in numerical analysis such as finite element analysis have enabled sophisticated analysis of brake squeal phenomena, but current design methods based on such numerical analysis still fall short in terms of providing performance measures for minimizing brake squeal, of high performance design drafts at the conceptual design phase. This paper proposes a conceptual design method for disc brake systems that aims to reduce brake squeal by tailoring the shapes of the brake system components based on the concept of First Order Analysis (FOA). First, the relationships between brake squeal performance and the geometry and characteristics of various components is clarified using a simplified analysis model. Next, a design performance measure is proposed for evaluating brake squeal, and a method for deploying component designs based on this measure is discussed. Finally, a practical design example is provided to confirm that the proposed method can yield useful designs for high performance braking systems.
