Well one definite symptom is when the wheel falls off. I had that happen many years ago in a company car. I heard some funny noises but ignored them because it was late and I was a long way from home. Like to pretend I've got more sense now.
Wouldn't really expect noise from pads to disappear when you turn but might be worth whipping the pads out, checking for stones, and getting some copper grease in there. Checking the things that are easy is a good start.
Hope nothing falls off.
