I see a lot of brake dust inside the drum area, I also see some heavy scarring & scuffing on the inside of the drum and on the shoe faces. I suspect someone has been doing 'Adios' burnouts before the car changed hands, and the brakes have bound themselves up harder.
It is also possible that if the brake booster has been tampered with recently the pushrod may have been lengthened inadvertently - causing the constant tension on the braking system.
Things that need checking at least.
