This study referred the brake squeal property of brake disc having small holes on frictional surface. The difference of sound pressure level was discussed using three types of discs. Measured brake torque variations of three types of discs were analyzed by FFT to estimate exciting force between brake disc and brake pad. The test data indicated sound pressure level of the brake squeal and the brake torque amplitude were significantly reduced when the small holes were opened. This study found that the area between disc and pad was representative parameter to control the squeal and torque amplitude.
