Front Drum Brake Issues

I'm currently having the same issue on my 71" Duster, front drums .....Drums new, shoes new, 10" drums...Spinning drums is difficult if not impossible ,and shiny spots showing on shoes, have set primary and secondary shoes as directed... The only way to get drum to turn halfway easy was to grind material off the shoe , where shiny parts were showing .... had problem on both frt drums ...
