Abstract

A brake rotor comprising a brake pad wear surface; a hat surface; and a decorative insert comprising an insert material, the decorative insert disposed on the brake pad wear surface, the hat surface, or both; wherein at least one of a friction coefficient between the decorative insert and a brake pad is substantially the same as a friction coefficient between the brake pad wear surface and the brake pad, a wear rate of the decorative insert is substantially the same as or greater than a wear rate of the brake pad wear surface, or a wear rate of the decorative insert is substantially the same as or greater than a wear rate of the hat surface; and at least a portion of the decorative insert is visible on the brake pad wear surface, the hat surface, or both.
