Abstract: A hand tool for use in adjusting a drum brake of a motor vehicle or similar mechanism. The tool comprises a member with a novel geometric configuration for the working ends. In accordance with the invention, a narrow neck portion is formed intermediate the working end and tool handle. The principal surfaces of the tool extend outwardly from the narrow neck to a wide portion and then angle down to a blade-like working end. The angled surfaces engage the wall of the drum brake such that the working end is urged into engagement with the adjusting means of the brake.
