An improved twist brake for the separable payload of a twist or spin-stabilized flare or smoke projectile is described. A pair of pivotable wings, secured at one end to a portion of a central shaft of the payload, is normally engaged by the inner surface of a guide shoe which prevents contact of the wing with the separable housing of the payload. Cooperable projections and slots on the guide shoe and the central support shaft prevent substantial axial and circumferential movement of the shoe, while permitting outward movement of the wings and the guide shoes when the payload separates from the housing. During such separation, the guide shoe is also separated from the wings so that the latter can pivot to their maximum extent to provide an optimum rotational braking action on the payload.
