In an electric motor brake, a friction disc includes an anti-rattle portion integrally molded therewith and reducing the tolerance gap between the motor shaft hub and the friction disc to minimize rattling of the friction disc during rotation of the shaft, and eliminating the need for a separate anti-rattle spring. In a first embodiment, the friction disc has a cavity at the inner circumference thereof facing the hub, and a cantilever finger extending into the cavity and engaging the hub and providing a cantilever bias urging engagement of the hub and friction disc. In a second embodiment, a bump on a slotted inner circumference of the friction disc provides the biasing portion, or may be spaced from the hub by a nominal clearance.
