    • The electrically operated disc brakes (10, 210) may include a high efficiency screw and nut mechanism (60) and/or a one-way clutch mechanism (230). The high efficiency screw and nut mechanism (60) includes a screw (86) with a screw thread (89) that has a predetermined pitch, and at least one nut (77, 97) disposed about the screw (86) and having an interior opening (78, 98) with a nut thread (79, 99) therein. The pitch of the nut thread (79, 99) is equal to the pitch of the screw thread (89), and the pitch diameter of the nut thread (79, 99) is greater than the pitch diameter of the screw thread (89). The screw (86) is driven by the electric motor (40) of the disc brake (10, 210). The one-way clutch mechanism (230) includes a sun gear drive member (252) which has oppositely disposed radial drive slots (257) through which extends a drive pin (243) that extends transversely through the drive shaft (241) of the electric motor (240). The sun gear drive member (252) is journalled within a cage member (281) which has oppositely disposed radial cage slots (282) into which extends the drive pin (243). The radial cage slots (282) are in circumferential non-alignment with the radial drive slots (257) of the sun gear drive member (252). The sun gear drive member (252) includes cam surfaces (253) receiving roller bearings (290) thereat, the roller bearings (290) extending through oppositely disposed openings (284) within the cage member (281) to engage an interior surface (297) of an annular housing (295). The clutch mechanism (230) permits the sun gear drive member (252) to be rotated in both directions by the drive shaft (241), but when reaction forces attempt to reverse rotation of the drive member (252) and electric motor (240), the clutch mechanism (230) locks and prevents such reverse rotation.
