drums pulling to the right

Your looking at the wrong side. If it pulls to the right,that means the right brake is working harder than the left. When it does this stop and see if one drum is much hotter than the other. But I agree you need to start with new quality brake shoes and have your drums turned if they are within specs. I believe 9” drums are discarded at 9.090 and 10” at 10.060. Did you replace both front brake hoses?
