In these days, not only braking performance but also comfort of passengers is required for the brake system of automobiles. Squeal noise of a disk brake system is one of the major problems for comfort. Many studies have conducted about brake squeal, but it has not yet been clarified with analytical solution. Squeal is random phenomenon and lacks repeatability, so making analytical model of brake squeal is very hard. In the previous study, simple model for brake squeal was proposed and strategies for reducing squeal noise of disk brake were investigated by simulation analysis. In this paper, simple experimental setup was made and the effectiveness of above strategies was inspected.
