Abstract
A mechanical brake actuator has rotatable and non-rotatable cam components provided with confronting helical grooves between which ball bearings are arranged to form a helical thrust bearing. A push rod, connecting rod or the like acts generally tangentially on a lever arm on the rotatable cam component for turning the latter. The lateral reaction arising from the lateral force due to the push rod is transferred from the rotatable cam component to the non-rotatable cam component by the helical thrust bearing, thereby avoiding the need to provide a separate journal bearing for the rotatable cam component. The rotatable cam component acts on a tappet member via an axial thrust bearing and an automatic adjuster mechanism.
