Just wondering how the guys that have done the SAS on the tacomas how you set up the brake lines. I was thinking about running them down the center of the axle and then out to the wheels for the flex but not sure.
Most I've seen just have a long one that replaces the OEM. That way you don't have to run new steel lines over to the center of the truck and then steel lines along the axle tube to get to the wheels. Remember to keep the rubber lines to a minimum because of the added resistance for fluid flow. (Same reason not to run a rubber gas line the full length of your vehicle.)
when we did my bros sas we just swaped in some extended ss brake lines in the stock location, we didn't run the lines anywhere out of the way or anything. Although, he will probably carry a spare brakeline.
