A segment of a seal assembly for sealing against a rotating member can include a main body extending between first and second sides and defining a radial outer surface and a radial inner surface for sealing against the rotating member, a plateau surface defining a portion of the radial inner surface, and a first transverse groove defined in the main body, the first transverse groove defining a portion of the radial inner surface and being for maintaining a pressure around portions of the segment. The segment can further include a primary pad defining a portion of the main body radial inner surface and being located at or in proximity to the first transverse groove, and can further include a secondary pad defined within the main body and located between the plateau surface and the radial outer surface, the secondary pad being radially concealed behind the plateau surface.
