Why reuse the old pads that are have been sitting for who knows how long and who knows how they were driven. Keep in mind the old springs could be rusted and prone to breakage. When you can get a drum brake rebuild kit from auto zone for less than 30 bucks, I'd do it. Why risk the car or your safety on old crappy brakes to save 30 bucks? The drums can be turned down and should be. AIT ozone again can do this for 10 bucks
