A self centering, floating brush seal assembly for a machine housing including a seal channel disposed circumferentially about a rotating shaft. The seal channel is typically configured to accommodate a ring seal. The ring seal is removed and a radially floating brush seal is installed in the seal channel but the brush seal is not fixed to the machine housing. The typical brush seal includes a front plate, a back plate, and a plurality of bristles sandwiched between the front plate and the back plate and having free radially extending ends disposed circumferentially about and contacting the rotating shaft. A radially extending rub feature is associated with at least one of the front plate and the back plate. The rub feature is disposed circumferentially about and contacts the rotating shaft.
