I won't mention who installed my new brakes simply because I can't prove it was their fault. Although, using basic forum tools here, one can find out easily.

My apologies for the confusion here. The loose lug nuts were the culprit. I mistakenly labelled them as wheel bolts (which have threaded posts). To clarify, the lug nuts (example) are tightened on to the threaded studs (example) of the wheel hub to keep the wheel secured.

As far as vandalism goes, I'd consider loosening/tampering all the lug nuts on one wheel as vandalism. Again, I have no proof so I'm just shrugging it off.

Bottom line - guys, check your nuts once in a while. + a dollar of truth
