All good auto parts stores, or tool distributors sell a brake tool that measures the inside diameter of the drum and then slides over the outside of the brake shoes on the front and rear individual wheel shoe assembly-like a go- no go- gauge. If you measure the inside of the drum then slide this tool over the shoes you can quickly adjust the shoes with the drum off. This will give you a more accurate adjustment on all four shoes, and eliminates the outside adjustment tool and eliminates pulling.The tool is fully adjustable for any size brake shoe assembly. Works for me.
