A seat height adjustment actuator includes a brake drum fixable to a seat and defining an outer brake race. A rotatable brake hub includes a floor with a shelf, and a wall around the floor with cam surfaces defining an inner brake race. A pinion fixed to the brake hub engages a seat adjustment mechanism through the brake drum. Rolling brake elements wedge between the inner and outer brake races to lock the brake hub at rest. A clutch drum defines an outer clutch race, and includes tabs extending between the brake races to displace the brake rollers, unlocking the brake hub, under actuator input. A centering bias element on the floor simultaneously engages the shelf and a projection of the clutch drum for centering the projection over the shelf at rest. A driver cam receives actuator input and drives rotation of the clutch drum.
