"Clinking" noise when I drive forward and scrub when I turn the weel...?

I just noticed today that when I drive forward, I hear a metal-like noise ("clinking") when I drive forward. The noise sounds like it's coming from the from passenger-side wheel well, but I can't really tell. I don't hear the noise when the car is in reverse--only when I drive forward or when I turn the wheel. The noice speeds up as my speed increases. I'm afraid to drive my car. Any ideas of what I should do or what it is?

I am guessing here but it is your caliper actually the shoes moving a bit in the calipers when they contact the rotors. If that is what it is that is perfectly normal. My passenger caliper/pad combination does this. I have inspected the brakes a couple times. They are perfect.
You might hear this when first applying the brake at a low speed that same clunk...

I had this happen in to my Maxima. Turned out to bent caliper cover.

Cool. Thank you. My car was hit last week on the opposite side. I hadn't heard the noise prior to the accident. We will see what the insurance company says.
