ABSTRACT OF THE DISCLOSURE A brake pad assembly having self-adjusting character- istics for correcting uneven wear of the frictional surface for use in a vehicular brake having a brake rotor, the assembly comprising a pad of frictional material attached to a rigid backing plate and having a circumferentially symmetrical central friction surface area fox engaging the brake rotor. The friction surface area has its center of pressure coincident with the surface area centroid, and is unsymmetrically increased should uneven wear occur, thereby displacing the area centroid toward the region of uneven wear and causing an increase in the surface pressure loading over the unaffected region of the frictional sur- face area and a corresponding increase in the wear rate of the unaffected region so as to return the frictional surface area to its original circumferentially symmetrical configuration and re-position the friction surface area centroid to its original coincident relationship with the center of pressure.
