    This seemed to help:

    1.) remove pads and clean back of pads, inside of calipers and pad separator spring
    2.) coat back of pad plate, the little tab on the front side of the pad that screw or cotter pin goes through and the separator spring with a light coat of Sil-Glyde brake lubricant.

    I think lightly lubing the separator spring is key as that thin piece of metal makes for a nice reed.

    So far so good

    I’m doing this soon. They scream on descents and it’s like nails on a chalk board.

    This is one of the best threads (I mentioned above) because it shows real understanding of the issue and fixes that address the underlying issue. Not sure if it would affect a bit of water-burn-off though that most bikes seem to encounter, on the other hand I've ridden with peeps that had howling brakes no matter the conditions.

    Tried Sli-glyde on both the back of each pad where the piston contacts the pad on front and rear SLX brakes. The howl went a way a bit quicker but they still howled.

    You have to do the edges to, just make sure not to get any on the pad itself. 10 miles in the snow Saturday, no noise at all. I just redo them once a year.

    Did you Sil-Glyde the spring too? If not, try that. (sparingly to not get it on the pad itself)

    Thanks for the detail. Will put on more liberally.

    Switch the pads, front to back or spin them around, inside to outside. The rotor will pattern the pad and draw the material out. Changing the orientation freshens up the biting surfaces, hushes the squeal with grip.

    Maybe the noise is a good thing? I was just going through some of my videos and when I was watching this one https://youtu.be/cSecxgL5Qdg, it reminded me of this thread.

    Inconsistent results from users in this thread could easily be due to different temps/humidity conditions.

    Cleaning the pads and rotors with IPA and a paper towel always eliminates the squeal for me. I also lube the pin and back of pad lightly with silicone grease. It is nice to check your brake pads anyway from time to time. The squeal seems to come back eventually when the temp/humidity/salt/glaze buildup are just right again. You can use brake cleaner or even starting fluid if you prefer instead of IPA.

    Just wanted to come in and add that I still think the issue is a glazing issue caused from moisture with some pads. Sanding the pads and rotors will solve the problem.

    Also worth adding I've been running the nukeproof resin pads with new centerline rotors and they have been dead silent.

    sunday, everything was pinched up tight. no water on the rotors and no brake noise. it is a wetness issue.

    That may be your issue. Mine seems more related to cold.
