Hi,
the second ( or was it third time ) I took the car in because of the noise I was told it was just corrosion on the brakes and I really cant remember if he said pads or discs. However when my husband took it in to get it fixed ( the noise is now constant ) he was told it was the discs. The front ones are a bit scored and worn and show corrosion the back ones are not bad but of course he was recommended to change all four ! The MINI is never garaged but generally it doesnt get much chance to sit around either. Its hopefully going to see my Father in law this afternoon for an independent mechanic's opinion !

As for the greenstuff pads, we thought as the brake pads aren't covered by the warranty (or TLC) it shouldnt make much difference and from the stories we were getting from the dealer doesnt look like the discs are really covered either
