A one-way clutch for an automatic slack adjuster, comprising: a first part rotatable about an axis in both a drive direction and a slip direction opposite to the drive direction, a second part that is driven about the axis by the first part when the first part rotates in the drive direction but that is not driven by the first part when the first part rotates in the slip direction, and a plurality of movable elements carried within receptacles distributed circumferentially about and projecting into one of the parts, the movable elements being displaceable so as to move within the receptacles in radial directions relative to the axis about which the first and second parts are driven relative to both of the parts and engaging corresponding surfaces of teeth that are immovably fixed on or form part of a circumferential surface of the other of the parts, wherein, in each clutch engagement state, at least two of the movable elements are biased radially relative to the first and second parts so as to have tips fully received between tips of the teeth that are immovably fixed on or form part of the circumferential surface of the other of the parts, and at least eight of the movable elements have tips that are biased radially relative to the first and second parts but are not fully received between the tips of the teeth that are immovably fixed on or form part of the circumferential surface of the other of the parts.
