Abstract
An automotive disk brake assembly installed in an automobile having a wheel. The assembly includes a floating caliper supporting an inner and outer brake pad and a brake rotor having a disk, and a hat, and wherein the hat is bolted to the wheel. A hydraulic cylinder is adapted to push the inner brake pads into the disk surface, causing the floating caliper to move bringing the outer brake pad into contact with the disk. Finally, the rotor is made such that a complete 100 kilometer per hour, 0.9 gross vehicle weight braking causes the disk to expand in thickness by at least 0.15 mm and to cool to shrink in thickness, relative to its expanded thickness, by at least 0.1 mm within 60 seconds of the cessation of braking, in an ambient temperature of less than 30° C.
