I replaced the rear brake pads on my 2001 Accord EX coupe on 12/14/2007. The rotors did not need any attention so I simply replaced the pads, using the Honda OEM pads I bought at the Honda dealer. I do most of my own work, so this is no big deal for me; it's prety straight-forward stuff.

After a few days I noticed a 3/4" wide band of rust developing on the right rear rotor, on the outer surface of the rotor (you can see it without removing the wheel), toward the center of the rotor, alongside the hub of the rotor.

I cleaned it up with a small wire brush, cleaned off the rotor and the outer pad with brake cleaning solvent, dried them, and put it all back together. It looked clean for a few days but that band of rust started to form again. I cleaned it off again and lubed the sliding surfaces of the caliper assembly with appropriate brake lube, and checked to insure the caliper pins were moving in & out smoothly, which they were.

The rotor again looked OK for a while but the rust has started to form again after several days. It's almost as if the inner edge of the outer pad isn't contacting that area of the rotor and not "wiping" it clean.

Has anyone experienced this? Any ideas?
