Hey guys first post not real sure how any of this works but i have a 1999 chevy z71 it has. 2001 rear end in it with disc brakes. the back right wheel squeaks every time it goes around but if you press the brakes it will stop if you barely hold on the brakes the squeak gets faster. it has new pads (Duralast ahold since the woman at autozone said that's the best kind to buy for these trucks) and it has new rotors and a new caliper on that side also has new universal joints and yet it still squeaks i just want to know what i have to do to make it stop any help would be greatly appreciated thanks
