发明名称 Single brake spring tool and method of removal of drum brake spring
摘要 A brake drum spring release tool includes a straight elongate rod member with a laterally projecting lever arm extending from one side and an extended hook member from the end of the rod member. The lever arm acts as a fulcrum when positioned on a drum brake spring simultaneously engaged by a hook member. Placing a generally lateral force on the grip end of the tool will cause rotational force imparted by the hook member on the spring typically with a mechanical advantage associated with the fulcrum of the lever arm to thereby release the spring from a drum brake shoe.
