Abstract: A resiliently flexible strip device mounts the armature of an electrically released brake for movement toward and away from the pole faces of the field shell, the armature either moving with pivotal motion or with linear motion. The resiliently flexible strip device may take the form of one or more leaf springs or may be one or more tongues molded integrally with the flange of a bobbin which forms part of the coil of the brake. A piece of flexible friction material is bonded to a curved pad on the outer face of the armature and automatically takes on the curved shape of the pad.
