You've got some big tires. If it was me, I'd get some better pads, front rotors, steel lines, dot4 synth brake fluid. I like the EBC rotors/yellow stuff pads on mine
You have a dual diaphram booster setup on your TJ, right (thought I heard all TJs had that)? If mine was a YJ on 35s, I'd consider pulling one of those dual diaphram boosters from a '95 YJ or just order it new and swap that in there too.
How's your tire pressure, also?
