XJ w/4w disc brake ?'s

[GREEN XJ]

Quick run down, building '98 Xj w/Ford Dana 60 front & 14 bolt rear. Front has dual piston calipers and rear is single piston 3/4 ton Chevy calipers. Any who has anyone done something similar or does anyone know if I will have to upgrade my brake booster or master cylinder, and if so tell what ya used.

I did the same thing (with a 44 front - dual piston calipers, and 60 rear - 3/4 ton chevys). I used a Corvette master cylinder (Napa#10-1423) and a Wilwood adjustable proportioning valve (like this first one listed HERE)
This setup worked well.

Thanks for the reply. I haven't got them under there yet and everything plumbed, so don't know what I going to run into. Thanks for any info.
