I have a 2017 SWorks Roubaix which I've put Dura Ace R9170 disc brakes on and as much as I love the bike, the brake noise is driving me insane. Have any of you had issues in the wet with these (or the Ultegra equivalent) brakes? It looks like the front caliper has a faulty piston which is slow to return, and doesn't return all the way. As the bike picks up grit from the wet road, it catches on one side of the disc (the bad piston side) and rubs until it clears. I've tried all the tricks - space the pads when I re-center, clean everything thoroughly, massage the piston (yes, that's a thing!) and it's still bad. Considering a warranty return of the caliper. The rear caliper leaked from new and I had to return that, so i'm a little rattled by the 9170 stuff at the moment.

Here's my bike. Last ones was the SL3 version of the same.
