For those of you that have moved your front brakelines to a center drop and then run across the axle, how did you do it? Did you use a single line with a split at the axle like the rear or still run two lines but have them drop in the center instead of at the sides? If you ran one line did you use the same proportioning valve and just block off one port or switch it? Also did you just run it down the engine crossmember then drop it to the axle? Thanks, I am considering doing this since I have my Blazer completely apart and wasn't sure how to go about it.
