Look at how your rear brake lines are routed....really take a look at them.

If you axle goes full droop for full stuff, will the break lines be stretched? If you think the answer is yes, I'll listen to your explanation as to how you think that will happen (assuming you still have the factory lines and are running stock or replacement rear upper arms).

What Stu is getting at is that your rear brake hose runs along the upper control arm on the driver side and attaches to the axle. Then hard lines run along the axle to the caliper or drum.

You do not need a longer brake line for a 4" lift.
