Hi,my front right brake rotor is heating up badly.Tried everything I can think of,new pads,have taken calipers apart ,cleaned and inspected ,ok,inspected o rings,they were plyable and no damage,pistons look good.Put it back together,same problem with the heat on right rotor,left is fine.Bled complete brake system with new Dot 4.So thinking it has to be the o rings,they are the original ones so maybe they have swelled or maybe the original brake fluid did something to them.Figured not a big deal,get a caliper rebuild kit from Harley maybe a hundred bucks or so,well you guessed it,Harley doesn’t have a rebuild kit for it.They want you to buy a 650 dollar,( Canadian)brake caliper.My question is can anyone send me a link for a company that sells a rebuild kit.The calipers are six pistons.Thanks
