Don't know If this is a break problem or not
 

Recently when I start driving my 05, I have noticed a scraping type sound coming from the rear, the pitch gets higher when I go faster and lower when I slow down (hope this makes sense). I have checked my pads and there is still plenty left...just had them done last fall (septemberish). I have no problems braking etc..any insight would be greatly appreciated

its not a break problem... but it might be a brake problem...

if it is the brakes then would need to be dragging to create the noise... so after driving, check to see if one side is incredibly hot (the easiest way to tell its dragging).

If it is dragging, do a search on here to see how to fix it.

More detail needed, 4 wheel disc I'd assume? Could be a sticking caliper or e-brake shoes f-d. They crack bad and maybe a chunk is floating around.
