...after I have put new pads and drove it 200 miles and still use the same pads??? Reason??? sqeal

(even if I applied the anti-sqeal gooo on the pads)
It's a 94 sl500 and it's the rear brakes doing it. Worse in the mornings. Thanks for all the help.
PS: I have PBR pads on and the car has 44K miles . Rotor history- unknown -I'm assuming it's original equip.
