Or at least if I did it myself I would be doing it by the book. Which you may have. But IDK ... didn't you have issues with brakes already and went to four piston calipers? What size are the rotors? Those are what I would have changed back when you had the caliper issue. Are they IceTech rotors or some other kind of heat shedding design? The front brake sees much harder use. It should be boiling hydraulic fluid as well. Does it? Maybe you are overusing the rear brake on descents? You don't have a drag brake so you have no choice but to make the front brake more of a player and take some of the burden on the rear. Just be careful and safe. It's dangerous enough out there with the crap that no one has any control over. Don't make matters worse and take on projects that have a direct impact on safety unless fully up to speed on the technology. I know, I know, I'm over a line, but some of your stories Foof ... just be careful.
