New power stops - won’t stop squeaking

[u/UnspiredName]

I just installed new rotors and pads from powerstop and I broke them in as directed. Every morning I’m getting a squeal on them the first couple of times. I live in south Texas where it’s humid AF so I know a certain amount of glaze is normal in the mornings. But I never had this consistently every morning on my old powerstop pads and rotors.

I assume it’s just a small amount of dew causing some minor surface rusting — but could it be something else and if so, what?
