For anyone following:
I know there’s been a few different solutions, but I wanted to share what I did to fix this issue. It’s been a week now, and the noise (exact same as shown in this thread) has not come back.
I ended up finding that my rear drivers side brake caliper appeared to be “sticking” when it was wet and cool, then once it heated up, it would finally release. I was ended up replacing the entire brake caliper, and problem solved!
However, I will add this side note: you need to make sure that the little cutouts on the piston line up at the 6 and 12 position in relation to the caliper. I found out that my old caliper was just fine, but those notches in the piston got out of alignment, and they were pushing my brake pad up/down and creating excess pressure on one end of the pad where it touches the caliper. This wasn’t allowing the brake pad to actually spring back away from the disk.
My recommendation, or rather what fixed it for me, is to take your caliper and pads off, check orientation of the caliper piston, and reassemble. If that doesn’t help, might be time to replace the caliper! When I checked all 4 of my tires, none of them made the noise, but as soon as I got to my drivers side rear, it was hard to spin and made that rubbing/scrubbing noise.
Good luck!
Nick
