rear brakes make a knocking noise on 2005 Saturn Ion

My rear brake shoes/pads and drums were replaced in August 2010 and when I stop at a light or brake the knocking noise appears. I took my car back to Tire Kingdom and they looked at the rear brakes and replace them with another new pairs of brake shoes/pads. Well, the knocking noise appeared again after a day. Do not know why the new brake pads/shoes and drums are making a knocking noise. Any advice will be greatly appreciated.

They are not been properly installed. They must be adjusted perfectly if not it would never be right. We can do that service for you for a bout $45 and you wont here that noise again.
