So this is from last night.

Just how dirty it was is plain to see!

Since it’s an anodized caliper, we got lucky. ★

Dust seal and

oil seal
Different rubber, different demands
Rubber is all about freshness!
Even after spending hours washing the caliper,
if it feels spongy right away, the right move is to replace the seals. ★
It saves time too.
That spongy feel turned solid. ★
