Boba I had the same problem with my green stuff pads. I used a silicone grease on the pad backs and guides and the worked for a short time but the squeel came back. Then I got some stuff at Advanced Auto parts called "Disc Brake Quiet" by CRC. It's It's a pinkish color and is a polymer that you aply and let setup before you reinstall the pads. Man, this stuff is awesome. I haven't heard a squeel or a squeak from my brakes for over 3 months.
