Bought my 2010 TriGlide Ultra Classic used with 9200 miles on it. First thing I found after I got it home, was that the parking brake didn't work very well. So, having worked on all my previous bikes, and having mechanical background, I too the wheels of to inspect the brakes and found them to be pretty thin and the rotors grooved. Because of the grooved rotors I have gotten very poor wear time. I have been reading your threads, and have to say the wizard seems very knowledgeable. I have read about possible automotive substitutes, and wonder if anyone has, been successful, going in that direction.
