A brake drum assembly with a cylindrical brake drum having an open end and a flanged end and an axis of rotation where an annular squealer band is formed on the brake drum approximately adjacent to the flanged end. A plurality of fracture apertures are formed in the squealer band and axially extend through the squealer band parallel to the axis of rotation of the brake drum. The fracture apertures are randomly circumferentially spaced along the squealer band and/or randomly angled relative to the axis of rotation. The squealer band is then cracked from the fracture apertures radially outward to the outer surface of the squealer band thereby providing friction dampening as vibration in the brake drum and squealer band cause relative motion within each crack. In an alternative embodiment, fracture apertures are formed in the brake drum adjacent to the open end and oriented radially inward where the brake drum is cracked from each fracture aperture toward the open end.
