Damn. That’s what I’d expect from a dot fluid accident. Or maybe 3 winters of salt on the roads. Officially the worst caliper condition for a modern mineral oil brake I’ve seen.
Do you live near an ocean??
it does indeed appear to be corroding, do you have bad salt in your area or something?
That appears to be a problem with the finishing on the caliper itself. It shouldnt corrode like this unless you park it in the ocean every day. I’d take it to a shop and try to get them to warranty it with Shimano
Get in the habit of drying off your bike every time it gets wet and it will last a lot longer.
That’s kind of insane to see that level of corrosion on the calliper and only the tiniest spot of flash rust on the disk — impressive!
