MightyVac evacuator makes it really easy. Good pedal as it should now. I don't understand why this happens to Crossfires. In all the years working on cars, I never had to bleed brakes unless a problem has occurred to allow air in.

I'm thinking that the seals in the MC had retained the memory of the relaxed position in the bore and did not expand, and this allowed the oil to leak past the seals as it does in a seal failure. The oil has to go past the MC seal if it does not leak anywhere else. I have not noticed this on my cars though.
I did suffer a near total MC seal failure once when stopping behind a bus in the UK, a guy standing on the rear platform of the bus was laughing at my panicked face as a furious pumping of the brakes stopped me just in time.
