Went with pure white instead of the off white cream??? I guess it should contrast well with the orange
I’ve had that issue once with an 88 Bronco, it showed up when there was moisture in the air like there has been lately. Never found a obvious smoking gun to what the issue was, but I can assume it was some sort of glaze on the brake shoes. I took everything apart and sanded a bit off the shoes and sanded the drums, they were old but had tons of friction material left, and when I put it back together it worked fine.
I also found before I sanded them, if I rode the brakes for 1/4 mile or so, they would heat up and work normal again until I parked the truck or did along freeway drive
