A down hole cleaning assembly is connected to a work string concentrically located within a casing string. In one embodiment, the down hole assembly comprises a mandrel operatively connected to the work string, with the mandrel having an opening therein. A pad member is received within the opening, with the pad member having a groove formed therein. Also provided is a wire brush member, operatively positioned within the groove of the pad member, for cleaning the internal diameter of the casing string. The down hole assembly further comprises a biasing member, operatively positioned between the mandrel and the pad member, adapted for biasing the wire brush against the inner diameter of the well bore. In the preferred embodiment, the wire brush includes a wire bundle, a brace disposed about the second end of the wire bundle, and wherein the brace is disposed within the groove of the pad member. The brace herein disclosed includes an open end and a closed end, with the closed end having disposed therein the second end of the wire bundle, and wherein the open end and the closed end cooperate to form a triangular shaped profile. The groove will also contain a triangular shaped profile adapted to slidably receive the triangular brace.
