The invention relates to a method for actuating a wheel brake assembly, in particular an electromechanical wheel brake assembly (10) or a mechanical system involving friction and having spring elasticity. To increase a braking force once a quasi-static terminal state of the wheel brake assembly (10) is reached, the invention proposes actuating the wheel brake assembly (10) for a brief period of time in the release direction and then to re-tighten it; the period of time of the actuation in the release direction is selected to be so brief that the braking force is reduced, if at all, only imperceptibly.
