when i just got my 04 S60R, i changed the brake pads on it right away and, i bought advanced auto parts brakes. they were the best ones they have " Blistex Brand" and they still squeked. when i had some work done on my Volvo at the dealer, i asked a mechanic about that and i recall him saying something like putting some kind of copper rings or plates, not sure, on. does anyone know anything about this because i am about to get new pads and rotors, but don't want to have the same problem...
