Chuck- not trying to hi-jack your thread, but this is all valuable to you as well.
Bruce and Rob- Thanks for all your advice.
I've tried everything mentioned over time-EXCEPT the silicone idea.
Rob, the noise I get comes from my front 4-piston Wilwood Dynalites. The pads are Sierra 31-YF "soft". I believe they're carbon-metallic. Are you saying to apply silicone to the pad backs within the "circles" where the pistons contact the backing? Sorry I'm so dense and not quite understanding. Won't that prevent movement by the pads?
Appreciate your advice and patience!
