well, each time let go of the brakes, i would get a loud sqeek from the drivers rear drums. sounds like a peice of metal scraping. it only happens when there is weight on it. when i jack up the truck and try to step on the brake then let go, it won't make the noise. but as soon as you drop it and have weight on it, it'll make the annoying sqeek again. by the way, it's 95 t100. any help would be great. thanks.
