Bad brakes or something else?! help

[ClassicalBor]

Noticed this saturday evening and it has gotten a little more progressive since. If i go over a rough bump sometimes i get a metal on metal rubbing sound from my front right wheel area... usually a moderate tap on the brakes gets rid of it. but then sometimes it happens when i also SOFTLY tap the brakes... and if i press the brakes any harder it will go away. I was thinking maybe it is my pads running slow or maybe something else like a loose ball joint, or some such. Can anyone add any more input on this situation for me before i spend money to get it checked out?

Bump, no one can shed any light on this?
