Caliper grease and brke pad gum is availible at any parts house.

What I didn't know was Harley has since made changes to the replacement pads. First off the locator pin is larger diameter and second is the paste that comes with the kit.

The paste is put on using a temporary mask (with 2 holes where the pistons are) that is put on the back side. Then you apply the paste to the area in the mask where the 2 holes are, using the supplied scraper to remove the excess paste. Remove the temporary mask and carefully reinstall pads being carefull not to get paste anywhere else. Went for a ride and no more squeal and the brakes worked like new. Also saw that my rotor where the pads run had started to lose that polished look and after a few more miles the rotors looked like they should look.

Have to say, I am very happy to have solved this squealing but, I am disappointed that the expensive Lyndall pads did not solve the squealing, in fact they polished my rotors while giving less stopping ability.
