Abstract
A brake pad having a surface coating operable to enhance the bedding-in process during normal operation. The surface coating may be formulated using one or more materials found in a friction lining of the brake pad. The surface coating may be formulated using only non-metal materials.
Claims20
A brake pad comprising:
- a backing plate having a mounting surface;
- a friction lining affixed to the mounting surface and having a tribological surface that is parallel to the mounting surface within a specified tolerance;
- and
- a surface coating affixed to a portion of the tribological surface using an adhesive and having a predetermined peripheral shape as viewed in a direction perpendicular to the tribological surface,
- wherein the surface coating is a composite material, the composite including a potassium titanate, and wherein the predetermined peripheral shape comprises a geometric shape asymmetrically applied to the tribological surface,
- wherein the tribological surface comprises a proximal end and a distal end opposite from the proximal end, and wherein the asymmetrical application of the predetermined peripheral shape comprises a continuous and gradual reduction in width when observed along a direction from the proximal end to the distal end.
