So I have a noise coming from my drivers side rear brake...it has a spot where it has metal on metal contact, or something of the sort. It's only on one spot and speeds up as I do, slows down as well..almost like something caught in the brakes...BUT I pulled apart my breaks and my pads are good, caliper is good, but have a few small pits in the rotor, could this be my problem? I don't know if this will help but its a 2004 Dodge Ram 1500 quad cab SLT 4x4.
