I've experienced frozen brakes on pretty much every car I've ever owned. It even happened on my T2 yesterday. You park the car in snowy conditions, the brakes are hot, snow melts and runs down onto rotors, calipers and pads, everything cools and freezes. It's as simple as that. No need to overthink it. Rust will not do this unless it was allowed to rust for a long, long time. And even then it would likely just squeal or grind until the rust is worn off.
