Took mine back to dealer and per repair bulletin,( REAR BRAKE )they ordered a repair kit Which included paste and new pins and noise hasn`t showed up since.Took about a half hour for them to fix...
Had the squeal problem for 4000 miles on my 08. Found a procedure on the following web site http://motorcyclemetal.com. Look under the touring family page and you will find the 2008 brake pad maintenance procedure. My original pads looked ok, but I went ahead and replaced them with Lyndall pads. Have ridden about 500 miles since I did the procedure and no squealing.
