That is correct and sensible. Replace your line one at a time and follow the old line with a new one.

That is one way to do it i personally try to remove as much of the old one as possible since i work at a dealership and i want customers to be happy, but if i was doing it on my own vehicle and there was a spot i could not get it out from i would just leave it.... it wont hurt anything, as far as the routing of it i would just follow the old line and use the old clips as best as possible and zip tie it where the old clips wont work.

No it was not

You can leave the old rusted line if you want,
but why.

You don't need to be told anything

Your either knowledgeable enough
to figure things out or not

You have to have the tools to cut,bend& flair
brake tubing.

You can run & secure it as you see fit.
Try to follow the OE the best you can.

There are no diagrams or tubing you buy and
install. That is a fabrication job you have to learn

Bleeding the brakes

Some vehicles have an odd way of bleeding them. My Chysler is one of them. Typically, you start from the wheel furthest from the master cylinder and complete one axle at a time, ending with the front wheel closest the master cylinder. On vehicles where the brake line is a tandem design, this is not the procedure. The brakes are bled diagonally beginning with the rear wheel closest the master cylinder and going diagonally to the front wheel, and then to the other rear wheel and then diagonally to the final front wheel, closest the master cylinder. Failure to follow the correct bleed protocol may leave some air in the lines, leading to a spongey pedal., depending on what type of brake line routing your vehicle has. Check your brake lines for leaks.

1995 ford f150 xlt 4x4 straight six 5 speed.. the metal brake line that runs on the frame from the front drivers side to the rear axle is busted nned to know the length? size of line? and size of fittings...

I can't tell you the length but the diameter of brake lines is commonly 3/16" and rarely bigger - some older vehicles and heavier vehicle use 1/4".

The size of the pipe is intuitive by simple comparison or measuring with a caliper but there is several different threads, lengths, diameters of pipe nuts in common use and it is important to get these right first time.

It is also very important the replacement pipe is formed exactly as the original, follows exactly the original route and is adequately secured.

When one brake pipe fails usually others aren't far behind and the failure of a pipe should signal a very close examination of the others, especially looking for corrosion scale or pitting close to the wheels. Replacing four or five pipes on a large vehicle can use a whole 25 foot roll of pipe.

It might be better to invest in a cheap pipe flaring kit and the materials to produce your own pipes - or remove the old pipes and ask a local repairer to make new pipes to those patterns. That was my job as an apprentice and I must have produced a mile of pipes for outside customers.

The brake pedal goes to the floor and I can not get them to pump up. I just changed my master cylinder.

So, I presume that you had brake pressure before the MC change, ....? What you need to do first is "bench bleed" the MC. There is a inexpensive kit sold for this purpose, get it at auto parts store, the kit has little hoses that hook up to the brake line outputs and route back into MC reservoir. Bleed until you get no more bubbles. Then hook up brakes lines and bleed the rest of the system. DO NOT let fluid level go down in MC, or start all over again. you may never get the system to bleed if you do not pre bleed the mc.

How do you replace a master cylinder on a 2001 ford taurus

Well, in essence you disconnect the brake lines, unbolt the MC and bolt the new one on, but you knew that.
What you need to know is you really must bench bleed the replacement unit, or you may never get it to go. What you need is a little bleed kit from aftermarket parts stores. This has hoses that screw in to the brake line fittings and route back into the reservoir, under the fluid level. Actuate the MC until no more bubbles....bolt the unit on the vehicle, (DO NOT let MC fluid run low, or start all over again), remove one of the bleeder hoses at a time and screw in the brake line.

Usually, you would bleed all of the brakes, next. You need all clean fluid at each wheel. and again: DO NOT let MC fluid run low, or start all over again.

How to replace brake master cylinder

The key issue is to prebleed the M/C. You can get a kit that has hoses that go where the brake lines go, and then route to under the fluid level in the reservior of mc. PRe bleed it, then do not let it run low on fluid or start again. Then unbolt the old, bolt in the new, bleed one more time, and observe no bubbles being pushed into reservoir, and remove hoses one at a time and screw in brake lines, then bleed the rest of the system.
