Really annoying sqealing from back brakes

[mcintyre_aerospace]

Has anyone else been gertit an annoying squealing from the back brakes while the wheel turns. I took the whhe off to change the tube and turns out it was causes by the springs that hold the brake pads together were rubbing on what look like cooling turbines on the inside of the wheel. Anyone know a solution to this before. Decide to just take a dremel after th to grind them down for more room. I don't care if I have to get rid of them completely the dang squealing gunna drive me mad.
