Abstract
An actuator for use in a drum-in-hat parking brake includes a wedge. A pair of tappets oppositely disposed from each other such that a tappet is positioned adjacent opposite sides of the wedge is included and a bearing is positioned between the wedge and an adjacent tappet. The bearing rolls along and between the wedge and the adjacent tappet and forces the pair of tappets apart from each other when the wedge moves relative to the pair of tappets. Movement of the pair of tappets away from each is used to force a pair of brake shoes into contact with a brake drum and provide a desired braking force on a brake drum.
