have you checked the brake pads rattling around in the caliper. obviously as the car is driven the brakes and pads will get warm causing the pad backplate to maybe expand slightly and lessen the noise due to the gap closing slightly , ive had to add 0.4mm to all my front pads after fitting the st disc and pad combo as the pad rattle was horrendous. I thought I hadn't tightened the bolts up. if it is that then it will be worst on a rough road at slow speeds.
