No need to change the brakes just make sure you have flex line from the frame to the caliper that can handle the drop. I have superlift lines on mine and they were long enough. I also relocated my lines to right below the frame rail for reasons other then the 52" but it added some length there.
I have seen a few guys come off the PV valve and T the front two lines together and then use a center drop off the engine crossmember with a rear T out to the ends the flex from there. Two much work for me and with the soon added hydro I have too many lines as is.
