A 25' roll of nickel copper alloy brake tube with fittings is $32 on Amazon; probably need two rolls for super cab.
You can pick up a flare tool at the same time for another $30- search Facebook marketplace as well for better deals.
Under $100 invested plus your time and you fix it correctly

Welcome to FTE

Well there was a reason why the metal line was done like that and my guess was it rusted out.
Beside rusting from the outside in they also rust from the inside out and you cant see that.

I was goin to say just what you did not want me to say, replace all the metal brake lines and the rubber hoses.
The hoses because over time the inside of the hose breaks down and falls apart and can block fluid from passing thru.

Replacing the metal lines is not all that hard just takes time.
Get a coil of the right size line in Copper - Nickel and ends to fit the line and a HF double flaring tool & mini tubing cutter and maybe a bender to make nice looking bends but not really needed with the C-N line.
Look on Youtube how to flare the line and make a few flares and when you have it down you can move on to making lines to fit the truck.
Pull 1 line off at a time and use it as a pattern just dont forget to put the fitting on before you flare it. Put it back on and pull the next line, etc.

Once the lines and rubber hoses have been replaced you only have the brakes at the wheels wo worry about and I would pull then and look them over and fix anything that may be wrong.
There is no need to get the truck running if you cant stop it.
Again it is not hard to do and you then know a rusted line will not blow out on you the next time you hit the pedal.

The Stop Shop 25 Feet of 3/16 Inch (4.75 mm) Copper Nickel Brake Line (.028" Wall Thickness) with Fittings

This is the size brake line you want. Most all of the fittings are 3/8" inverted flare on our trucks. There are usually a couple different sized fittings ones on the master cylinder. You can reuse old ends if they are in good shape. Most importantly, don't buy the cheapest double flare tool. Get a decent quality tool.

 

Make them, it's easy. For the most consistently nice flaring, I do like my Cal Van #161 in line flare tool ... besides, you'll need something anyway.

 

What is the originial question? What did I miss? Did the OP edit out his question? All I see is a couple pics of some extentions for the PARK brake cables.

 

As I recall, he had or bought a truck that had funny feeling brakes, and after pulling the bed for some reason, found the brake lines were plugged shut behind the cab back .... hence discussion brake lines, etc. I see the pictures, but I don't believe was any pictures before his edit. I don't think he even mentioned brake cables.

 

Well those are e brake cables in his pics and the thread says nothing about plugged brakelines. But no big deal, because as alwasy you guys have him all new "brake" lined out. Lol

 

k cool... I thought I was missing something too as there were no questions and nothing about E-brake cables...

As a reference, I've just fully plumbed my f100 (now short box) with all new lines. I used a full roll of 3/16" plus about 6 feet of a new roll. 2 full spools (25') is more than enough. Best advice is to buy really good quality fittings though. Don't cheap out on those.

 

Yep that is how I remember it also and no pictures.
You can see they edited it at 5:13pm yesterday
