1997 taurus brake line blown out!

How do I replace the brake line running from the front to back under the driver side. Line blew out and that is where the fluid is coming from.

Going from the leak, follow the line to the front and back finding the next connections. Take the old brake line off and either get an exact replacement from Ford or take the old one to a parts store and they should be able to join various lengths to come up with the same as what you have. Get a brake line bender while you are there, they may have one to rent/lend, to put in all the correct bends. If you try to bend with just your hands you will most likely kink the line. After replacing the line you will have to bleed the air out, then make sure you don't have any leaks.

These lines seem to rot through under the drivers seat area. If the rest of the line is still in good condition, I would cut out a short section with a small tubing cutter, Flare the ends and add in a short replacement section using inside flare fittings. ( Do not use Compression Fittings)

I just changed these brake lines due to the same leak condition. I used the new alloy line and it was relatively easy. The guys at autozone say they will not rust.

However, after bleeding the brakes, the pedal still goes to the floor. I am wondering if I connected the lines to the rear brake load sensor (where the two lines from the front and the rear brake lines connect) right above the proportioning valve wrong. Would that cause the problem (essentially no brakes)? Help!!!

again have it smarty pants i said pump brakes

Since you replaced a sizeable amount of brake line, I suspect you just don't have all the air out of the lines yet. One thing that may help would be to pick up a vacuum check valve, the biggest you can find at the auto parts store, and some clear tubing that will fit both your bleeder screws and the check valve. Position the vacuum side of the check valve away from the bleeder screw and connect that end to a reservoir of some sort. Crack the bleeder screw open, make sure the master cylinder is topped off with fresh fluid, then slowly press the brake pedal all the way to the floor, slowly let the brake pedal return to the rest position, pump again, etc. Do this probably 5 times and check the tube between the bleeder and the check valve. Is it completely full? If so, close the bleeder and move to the next bleeder. If not, pump the pedal a few more times. If you have a friend that's available you can have them watch the tube or pump the pedal as well.
