Depends on the design Older big US vehicles had relatively flexible disks sandwiched between heavy iron flywheel/pressure plate. They were wavy right out of the box, which added to the progressiveness of the release. These were VERY tolerant of disc warpage. If they chattered, it was due to hot spots on the flywheel and/or pressure plate, not warpage on the disc. Imports and later US cars with more rigid discs and lighter pressure rings had more problems with runout. Rex in Fort Worth
