Yes, try this:
Remove the brake shoes. If they have 1/8" or more left of material, do not replace them. Sand all of the glaze off them, then spray off all of the grit from sanding with brake cleaner and let dry. While that is drying, also sand with 200 grit or emory the drum where the shoes contact. remove any corrosion or rust. Also spray clean with brake cleaner and let dry. Re-assemble and marvel at how much better the de-glazed brakes work!
