I have swapped the front and rear axles in my 2012 JKU to a SD60 front & 14B rear. I am currently having issues getting enough volume to work the brakes. The pedal will build pressure and then will lose pressure once it sits. MC and Brake Booster has been replaced. Do I need a larger bore MC? If so, what are my options?

This ^^^ You need to do an ABS bleed. A scan tool will make this possible and it will make a HUGE difference, even with the factory MC and booster.

Thinking it would cause more issues since the tone rings might be different?
That is what I've read. I didn't know if I could use my programmer to change the front to read the current 60 tooth tone rings and splice the rear in.

I think Artec has the conversion for the SD60 front
Sourcing parts for the j8 brake system is less than the mopar equivalent. crown automotive makes the j8 MC you can order seperately as well as the brake booster. The reservoir for the MC is off a durango 4.7/5.7. 2006-ish to 2008, sourced from wrecking yard or part direct ie rockauto.com
J8 dual vs single stock diaphram brake booster and the largest MC bore available for a JK is the J8 MC.
