So I am puttin on a new lift and i orginally went into it thinking I was gonna half to buy new brake lines anyways but I cannot remove the fitting on the axle in the rear that connects to the T block that is all the line I plan to replace is the rear and front is there a kitt for all new brake lines and what is the tool and how do I do it, if someone can help me out and walk me threw it step by step it would be appreciated? thanks for the help

 

From what I can remember, the new lines come with a new 3 way block. There's a bolt holding the 3-way block onto the axle. That has to be removed. The two lines going to both brakes have to be twisted off too.
