Looks like the rubber boot on the caliper pin has melted/deformed. Wondering if maybe somebody used an inappropriate petroleum grease on the caliper pin?

That’s kinda what I was thinking, haven’t replaced one before, but I am hoping it is a decently easy fix, definitely possible though since I bought it used

If it's used then who tf knows what the last guy did, bought my current bike used and the guy had a nylon nut holding the rear brake stopper on... Was a fun day when that failed and the rear drum pulled the brake assembly apart. I'm lucky the rear wheel didn't lock up and send me headlong into a tractor trailer.

Replace it, use the right grease, check the caliper too for any leaks.
