Everytime when I put the car in reverse, i get this annoying squeeling noise coming from my right wheel well. I checked the brakes and the pads are fine, it only happens whenever i go into reverse. Any idea?

 

How'd you check the brakes? Did you only look at the outboard pad? I've seen where the inboard pad wears down faster than the outboard one. (Sticky slide pins.) The inboard pad has the squealer-tab. I've also seen the squealer-tab bent so it starts squealing when there's still a bunch of material left on the pad.
