I purchased new rotors and brake pads for the rear of my 1990 300SE. Before the installation I never had a brake squeal problem in the 120,000 I have had my car. I purchased the Rear Brake Discs Made by Balo and PBR Brake Pad Set Metal Master. Now the brake squeal is un bearable and ear piercing.
I applied red Napa anti-squeal grease to all four rear brake pad backings. It stopped the squeal for about 350 miles and now it is back. Is there something I can do to prevent this or do I have to buy new pads?
Any suggestions?

THanks,
Dan
