Here's the parking brake conversion for a Dynatrac XD60 with their brakes. I believe if you have a Rubicon or other trim with the bigger brakes you can keep those and retain the factory brake cables. I started with a Sport S, those brakes suck badly on 35s, I opted for the massive Dynatrac brakes. Im doing 37s this go around, maybe 40s in the future.
Then I got wheel speed sensors sorted out, brake calipers reinstalled. Ready to install Camburg brake lines (really well made lines) and bleed the rears as I install each one. If I make the swap quick enough and get em bled out immediately, air shouldnt make it to the ABS module. Then I cleaned up everything, got it back on wheels, supposed to rain next several days. Hoping to drop front axle and get new one in place next weekend.
