So

We also swapped out the tires for some Pirelli Diablo something-or-other.

The calipers are pretty old too.

Racing-specific corrosion on the left side

Cracking on the left side
Since it’s held together with a union, it’s still fine for now,
but once the crack reaches the nipple, it’ll start leaking.
The old gold racing calipers I used to run had cracking too.

This one’s the right side with corrosion

No cracking

The rear’s in pretty decent shape.
