While riding yesterday I started smelling hot brakes and noticed the trike being held back when giving it gas, so i pulled over and noticed the right front rotor was very hot. so after setting for a few minutes took off again and had no more issues. Now this happened before but to the left caliper and it and the rotor was replaced under warranty. So we got home and I pulled the caliper and pads and when pumping the front brake only one piston was pushing out, so I cleaned them with brake clean and a tooth brush and after that i was able to nearly push them in by hand. Tonight I am going to pull the left caliper and clean those pistons, and of course we are leaving for a all weekend ride this Friday so there is no way to get it looked at for probably a month. Now I have done this on my 2002 Road King when the front brakes felt spongy and the handle would come back almost to the grip so I hope this corrects my sticking front calipers. And this bike does not have ABS the brakes are linked, has anyone else had issues with the calipers getting stuck. The bike currently has almost 27,000 miles on it.
