CPP Disc Conversion - Good and Bad

[metalprelude]

Finally finished the Classic Performance front disc conversion on my 61. It looks amazing. I hit some speed bumps around a stripped brake line and disentegrated ball joint bushings but, overall it was pretty easy with some googling.

Energy Suspension makes some really affordable bushing replacements and I went ahead and replaced the outer tie rod ends with new Moog pieces. Additionally, I learned how to use a flaring tool and took the opportunity to pressure-wash the A arms and suspension.

Here's my remaining issues and I'd love some guidance-

1. My factory steelie rims are too small for the new brake setup. Anyone know the wheel specs required for the CPP Conversion?
2. I can't get the brake pressure to build. I've verified there are no leaks but, even with a Mityvac, I can't get the hydraulic pressure to build. Any ideas?

I attached a before and after shot.
