Rear brake noise

Im applying that orange squeak stop goop to my pads as we speak on my 2012 Caravans rear. The shim had physically shifted over about 5mm on one side so I just ditched them and put this red RTV type stuff on the backs and reinstalled. Well see. I would not hesitate to grease all the sliding points on the drum brakes per the FSM. They highlight all the rub areas, quite a few!
