Default Brake Squeal is Driving Me Nuts!

OK Guys. Im at my wits end with this darn front brake squeal. The squeal comes in right before the bike comes to a complete stop. The brake pads are HD and look good so, short of replacing them, here is what I have tried:
Sprayed the back of the pads with Permatex Disc Brake Pad Anti-Squeal, Sanded the glaze off of the pads with 80 grit paper, Beveled the leading edge of the pads, and De-glazed the rotors with steel wool. After doing all of that, they still squealed so, I removed the pads again and put anti-seize grease at all metal-to metal contact points and the caliper mounting bolt sleeves. It still squeaks. It sounds like some kind of harmonic squawk instead of a high pitch squeak. At this point, I am not opposed to replacing the pads. Any ideas? Thanks

Sounds like the pads are playing your rotors like a phonograph, If the rotors are in pretty good shape, maybe you could swap sides with the rotors and change the direction your pads are coming across the rotor....

The rotors are not grooved or worn but, I do some hot spots on them. Might be worth a try to swap them around.

This might help. Remove the pads and clean the Permatex Disc Brake Squeel "crap" off of them. Wipe a thin film of silicone based grease on the perimeter of the caliper piston that come in contact with the disc brake pad. This has resolved the problem hundreds of times for me in the automotive and motorcycle field. Good Luck.

Di-electric grease ? I'll give it a try.

Do both. Di electric grease and flop the pads to other sides. Also grind off about 1/8 of front and rear edge of pads. ( don't breath that crap) Damn Harley pads I have had no luck with noise or stopping
EBC sintered and be done with it.

Well crap. No luck. I swapped the rotors and followed Uncle Larry's instructions and the squeal is still there. So... EBC Sintered huh ?
