A gas turbine subassembly having a stator, a rotor, and an annular brush seal which is attached to the stator and whose free end is in line-to-line contact with a first circumferential portion of the rotor's outside surface during a first rotation/load state (such as a full-speed/full-load state of a power-plant gas-turbine rotor). A longitudinally-adjoining second circumferential portion (such as a groove) has a smaller diameter than that of the first circumferential portion. The rotor and stator together undergo a predetermined differential thermal movement when the rotor transitions to a second rotation/load state (such as a turning-gear/no-load state). During such movement, the free end of the brush seal moves radially inward and longitudinally across the second portion, preferably without any contact, to minimize or eliminate brush seal wear.
