How To Run Steel and Rubber Lines For Disc Brakes In Trailer

Question

Question:

From what I am reading, I can not picture how the lines are supposed to run under the trailer, mainly from wheel to wheel. I have seen rvs with disc brakes installed, so Im confused as to how the lines stated in the add would actually connect.

I understand why it would seem confusing running the steel and rubber lines for disc brakes on your trailer that come in a disc brake kit like part # HSE7K-TR1. The steel lines are the main lines on the trailer and the rubber lines extend to the brake assemblies. I have attached a tandem axle diagram for your reference.
