Abstract: A tool for manually rotating the star wheel of a brake adjuster is provided having an elongated body with two spaced projections extending substantially normal to the axis of the body and preferably in opposite direction. The projection carry at their ends opening or similar arrangement for engaging individual teeth and the tool is slotted between the projections to accomodate the width of the star wheel. The tool provides an alternative for manually turning a resisting star wheel by the tedious one-tooth-at-a-time turning required by the use of so-called adjusting spoons.
