A disc brake assembly having a rotor defining a rotational axis and including a barrel portion and a disc portion extending generally radially outward from said barrel portion, the barrel portion including a tone ring receiving portion with a generally cylindrical inner surface having a tone ring receiving surface and a groove with an axially outer wall, an axially inner wall and a radially outer bottom surface; a generally annular tone ring positioned concentrically within said cylindrical inner surface of said tone ring receiving portion and having a generally radially facing outer surface; a resilient biasing element received in the groove and having a generally annular shape including a plurality of substantially linear segments and corners, the resilient biasing element may be shaped such that it is flexed when seated within the groove so that the corners are urged against the radially facing outer surface, and the substantially linear segments are urged against the axially outer wall and the radially facing outer surface of the tone ring to prevent separation of the tone ring from the rotor during use. In one aspect, the biasing element is formed in the shape of a regular polygon, such as a dodecahedron.
