Back from the dealer. So far, the squeal is gone. I did a 50 mile ride home with plenty of stops and, so far, no squeal. Here's what they did:
1. Cleaned both rotors front and back with a clean rag and brake cleaner;
2. Removed the pads and applied 'NAPA Brake Quiet' on the metal backings of the pads. This is a red-pinkish silicone based goo which was applied liberally, allowed to dry, and then the pads were re-installed.
The service manager rode the bike up and nailed the front brake. No noise. I'm not certain that he is convinced that this is a long term fix though. Time will tell. In the meantime, there is the recipe for others to try and see if it works and for how long. -Ken
