Brake lines..

So i have a 1972 f100 long box that needs some brakes. It has been lifted and looks like someone tried to do custom brakes??.. They have a splitter on the front and rear axle that branch off to each wheel..(one line to the back that splits, and one to the front the splits) Does that sound right?? Plus I work at a junk yard and we have numerous Fords from the 80's but not so anything before that...

So my question should i just try to make some new ones?? Or would any lines from the 80's trucks be legit to use?? Oh and is the one brake line to each axle that splits safe or should i have that redone??

Tyger, If you will be doing a disc upgrade in the near future you will use a line to each front wheel with a single line to a splitter on the rear. The brake lines are like any other plumbing, they hold the fluid that moves the plunger that moves the shoes.

I have never heard of any legal issues concerning brake lines, other than you must have them.

What's your plan for the truck?

The system you have is exactly the way it came from the factory.

Bill, Did those trucks have front discs?

Am I misled thinking proportioning valves were only used on disc/drum sets?

My 67 with all drums had a proportioning valve. When I upgraded to disc/drum, I had to change the proportioning valve also.

John, I've had a couple guys swear up and down that some of the very last produced 72 F100 4x2 trucks had factory front discs. I've never seen one nor have I ever been able to verify it with a reliable source. I also wouldn't totally rule out the possibility because I've found quirks in the 67 - 72 trucks that don't show up in parts books or service manuals.
