Hello Everyone

I was driving home last night from work and all of a sudden I could hear somthing rubbing in the front. Sometimes it would sound like the wheelwell rubbing on the wheel and sometimes sounds like something is grinding .

When I got home I lifted the car up and went under to see if I could find anything and noticed nothing.

It sounds like it is coming from the driver side wheel well more then anything and I have just noticed that there is a divit in the rotor on the driver side front

I know this is a long shot question and very vag but any help would be great

Thanks,
