In this study, a major cause of judder, disk thickness variation(DTV), was investigated by examining the correlation between graphite distribution and the wear properties of gray, cast-iron brake disks. To test the manufacturing methods, gray, cast-iron brake disks were manufactured in a commercial facility in four different processes. The wear properties of the four brake disks that were manufactured differently were confirmed to have a DTV profile after the Dynamo tests. Results showed a correlation between graphite distribution and the wear properties. A brake disk with mold modification by using a vertical molding machine was produced at a controlled solidification rate. The brake disk with mold modification by using a vertical molding machine had a microstructure consisting of lamella graphite and Type A in a distribution of graphite(ISO 945-1) that was between 0.12 mm and 0.5 mm in length. It had the most uniform wear property from a vertical molding machine, compared to a brake disk manufactured in a horizontal molding machine.
