The last time I replaced the drum brakes on my Corolla I vowed never to do it again without scheduling spring work. With a little research, this tool has saved many injured fingers and broken springs. I'm not sure how well this would work on the big drums you find on trucks (although I think it's ok), but it worked great for economy/sedans.
