Is severe brake rotor and caliper rust safe to drive on?

Heavy corrosion and pitting on brake rotors and calipers can occur from winter road salt and outdoor parking, especially on certain vehicle models. While surface rust is common, severe rust gaps where the disc meets or caliper binding can indicate a dangerous issue that requires immediate inspection or replacement to ensure safety.

“Just bought a 2013 civic and the wheels look like this severe corrosion even making gaps where it meets the disc. Is this safe to drive or can they be refurbished?”source ↗

“Previously dealt with seized caliper which is apparently a common issue for my year of car (2014 Honda CRV), and living in the midwest and outdoor parking I'm a bit used to things getting rusty. Just was curious if it was cause for concern or if that's just the way things are.”source ↗
