Changed Rear Brake Shoes (drums) on 09 Silverado and hear a rubbing noise

What is your question?

2009 Chevy Silverado 1/2 ton. I changed the rear brake shoes and am hearing a rubbing noise while i am driving. The brakes are working fine, but I forgot to put grease on the raised pads on the backing plate. Any suggestions?

How long has your 2009 Chevrolet Silverado 1500 had this problem?

I just changed the brakes yesterday and as soon as I drove off I could hear it
