Let me try to help here-Did you adjust the brake shoes properly and also turn the drums?
Brake noise in drums is poor contact between the shoes and drum. Heel and toe contact between the shoe and drum is often the culprit, and the cure is to either replace the shoes with new ones or to resurface the drum slightly to increase its inside diameter. New shoes are ground with a slight eccentric to compensate for drum wear. This moves the point of contact away from the ends of the shoes toward the middle. In the old says, mechanics used to arc shoes to match their shape to the drum. But with the concerns about asbestos, shoe grinding is pretty much a thing of the past (though it might make a comeback if and when asbestos is totally out of the picture).
Other causes of drum noise can include weak or loose hardware (replace it), and vibrations between the shoes and the raised pads on the backing plates (apply brake grease).
