Today when I left the house I noticed at squeaking sound, almost a metal to metal scrapping sound coming from one of my wheel wells. As I proceeded to work the sound continued when I would apply the brake and at some points just whenever I was driving. Now the last week was pretty nasty here in the northeast so I was thinking maybe it was just some cinders and other build ups from the road treatment on my brake pads. I checked the pads thru i-drive and they said they are still good. I was probably going to take it after work and try and hose off the well and wheels. Any thoughts?
