You could install your axles and hook your brakes up and try them first. I had the same combo for years and used the stock YJ master and locked up 39" Iroks.
When I swapped to a 60 rear steer I used the same combo ( just hung the calipers off the frame ) got done with the axle swap and my brakes sucked, couldn't figure out why.
I know now I had a bad caliper in the rear and I didn't notice it till I completed the swap.
So all that aside I say try your stock TJ master and see. If you have meh brakes then try swapping to a larger boar like the dodge 2500 truck master and if that still doesn't do it there is always hydro boast.
1993 YJ 4.0 60 Front, Rear steer 60, bolth spooled, 5.38's, 700r/241 39.5 iroks and beating it like it owes me money.
And on the 8th day, God created the 14 bolt....
