After using the front brakes to prevent the bike from rolling backwards, you get a clanking noise the next time you use the front brake to slow forward movement. This is caused by the brake pad striking the pad pin. The pad pin hole is too large and allows too much back and forth (not side) movement of the pads. While helping a neighbor with brake pad replacement on a 2008 SG, I noticed that the rear brake pads were identical to the front pads but the rear pad pin was larger in diameter. I purchased two rear brake pad kits and used them to replace the front brake pads on my 2008 Road King. I did not use the antisqueak paste, just the pads, pin and retaining clip. The pad pin from the rear kit is a little longer, but does not interfere with putting the caliper screen back on. The shoulder of the pin was slightly shorter but torqued to specs without a problem and the groove for the retaining clip was in the proper position. The pin is larger in diameter but still allows sideways movement of the pads. The larger diameter pin has eliminated the clanking noise that used to occur with the Brembo front brakes I've put a couple hundred miles on since the pad replacement and have had no problems whatsoever. I'm very happy to be rid of this noise, it had aggravated me for two years.
