That is a strange one dude, pad should not be moving. On a lighter note i have had the strangest rattle in my car for the past week. could not put my finger on it. It sounded like the typical rattle/squeek that R50's tend to have but this was new. Spent all last week trying to find it. Eventually coming home from knockhill i found when i pressed on the passenger rear floor it stopped. well i could not understand. I was out today with the wife and said to her she looked about while I was driving, she than pulled the bottle of fanta in the middle cup holder out and it stopped. What an arse, I cannot believe it was a bottle of juice causing this.....I am a fool
