Hmm, I've never heard of "pad deposits". When I've turned warped rotors on  a 
brake lathe, lots metal is removed in order to get them true again. They  are 
truly "warped" The only surface abnormality I've seen on brake rotors are  
"hot-spots" that are metallurgically fried and become glazed or grabby, and rust 
 imprints from long-term parking. Rusted areas also become grabby.  I've  
never tried an "Italian tune-up" but it sounds plausible, if, if, &  if.
