<p>A brake adjuster for adjusting the working clearance of the shoes of an automotive drum brake. The adjuster has three co-axial elements, a first end element having a head portion for engagement with a first brake shoe and a threaded stem portion, an intermediate element in threaded engagement with the first end element, and a second end element having a head portion for engagement with a second brake shoe and a stem portion slideably connected with the intermediate element and free to rotate relative thereto. A reaction member is mounted on the intermediate element, and a toothed ring gear rotates with the intermediate element and is axially located between the second end element and the reaction member. A leaf spring acts between the second end element and the reaction member for pushing the second end element away from the intermediate element.</p> |
