Rear Driver Side brake noise

[JaseGill]

Hi guys,
A relatively new Mini Cooper 03 owner here.
I have a slight noise coming from the rear driver side brake. I cant see any signs of problems and the disk doesnt get any hotter than the one that makes no noise.
Its mostly at slow speed, generally during pulling away and slowing down.
Ive heard that it could be dont to the fact that all the brake pad sets now no longer have asbestos in them and have a higher copper content. Ive also heard that Mintex and Ferrodo dont make the noise, I think mine are AEP (could be wrong) as the brakes were all done just before I bought the car.
Anyone having the same experinces? Im guessing its not a snag and Im concerned obver nothing being a new owner, I figured Id ask though
Rgds,
Jase.

Just guessing since you don't describe the noise at all, the pads may be dragging some and vibrating in the caliper. It could be caused by an improperly adjusted parkling brake (most likely), sticking piston or a pad that is too loose in the caliper. Some pads just make more noise than others due to pad composition or poor quality control .
