BurtonBoy, on the Big Brake FAQ it states that the 2G AWD and 2G FWD uses different brake lines; however, I contacted Norco Mitsubishi, and they told me that all 2Gs have the same brake lines. Furthermore, I did the big brake upgrade, and I did not change my stock brake lines. The 2G AWD brake calipers will fit our stock 2G FWD brake lines. You do not need to change them unless they are worn out or unless you want stainless steel ones. On the bracket topic, you NEED the bracket off the 2G AWD in order to fit the dual piston calipers. Good luck.
