1. A brake pad, comprising:
a back plate having a mounting surface;
a friction lining having a tribological surface and coupled to the mounting surface such that the tribological surface is parallel to the mounting surface within a specified tolerance; and
a surface coating affixed to the tribological surface, the surface coating being configured to establish tribological contact of the brake pad with a brake rotor, wherein
the surface coating is affixed to the tribological surface using an adhesive, the surface coating having a predetermined design, and wherein the surface coating is configured to create a transfer layer of material onto the brake rotor during tribological contact of the brake pad and the brake rotor, wherein the predetermined design comprises an asymmetrical distribution of surface coating with respect to the surface area of the tribological surface, wherein the friction lining comprises a width dimension and a length dimension orthogonal to the width dimension and defining the friction lining between a proximal end and a distal end,
wherein the predetermined design of the surface coating incorporates one or more of a graphic design, text, or a photo-realistic image,
wherein the asymmetrical distribution of surface coating comprises a greater coverage of the width near the proximal end and a smaller coverage of the width near the distal end,
wherein the predetermined design of the surface coating comprises a geometric pattern, the geometric pattern comprising a repeating pattern of concentrically-arranged circular sections or a repeating zig-zag pattern.
