Like the title states, I have a squeak coming from my rear drums. Whenever I release the brake, I can hear a squeak coming from them. It only happens when sitting still or at very low speeds (below 15-20 mph). It squeaks no matter how quickly I release the brake as well. Fast or slow, same squeak when the pedal is almost completely released. It still does it no matter how long or hard I have been driving. It's fairly loud that I can even hear it when I have all the windows up. Any help would be great. Thanks in advance!
