i haven't seen this exact point covered, here. i'll be installing my "pre-owned" rancho 4" lift kit before too long. i'd rather not replace the brake lines if i can use the stock ones safely. it looks like on the rear, i can just make a bracket a few inches taller to raise the t-fitting. easy and cheap. the front brake lines could be more of a pain, but again, it looks like i could just make some longer brackets for them. have any of you tried this and had problems with clearance, flex or anthing else? suggestions? pics?
