When I bought my ranger, the previous owner disconnected the rear brakes because they were broken. Fast forward to now, and I just swapped the axle with an explorer axle with disk brakes. Now I have to reconnect those lines to finally have rear brakes. I have some pictures below that I think are where they connect. The first I think is the line that snakes through the chassis to the rear, and the second is where the line connects to the brake booster. Can anyone confirm this, and what is needed to connect these back together?

 

The front connection on master goes to rear brakes.......rear connection goes to front brakes, on pretty much all vehicles, not a Ford thing

This single line runs down to Rear ABS unit in the Drivers side frame rail, then single line from ABS unit down that frame rail to the rear where it connects to Flexible brake line that connects to top of differential housing "T", that splits line to the 2 wheel cylinders

The line that runs between ABS unit and rear flex line often rusted out between gas tank and frame rail so needed a new line run, this happened on 2 of my Rangers, same spot
Easier to just push a new line thru than to drop the tank

The ABS unit often failed, and was expensive to replace
You can by-pass it and put in a Variable(adjustable) proportioning valve, which actually works much better that Ford rear ABS did, lol

 

The rear connection on the master cylinder is the one connected. Wouldn't that make the front brakes go out?

 

Yes, unless someone connected them to the front port of the master
