If I was to bet, I would say air
I’m on my iPad and I thought I read your whole post, but I missed your very pertinent point at the bottom. Those 4 pot calipers are holding a lot of fluid under extreme braking. Also, I have no records indicating that the fluid has been changed in the last few years so there may be who knows what in the system.

I’ll try to change the fluid and purge the brake and clutch systems (also ensuring to engage PSAM and ABS) next week. I’ll update as soon as I have the result.
