my friends bought a second hand bravo and she had a bump on the rear pass corner, i took the bumper off to start the work on it which meant taking the rear n/s wheel off. the wheel nuts are thread bare and the bolt holes are in a bad way, after checking all wheels they are the same, only one nut holds the back n/s !!!!! can a new drum simply cure this or would you pursuee this by means of the police as its an unsafe vehicle ??
