Brake Fluid Leak problems of the 2006 Chevrolet Suburban

I was pulling into my driveway at approximately 15 miles per hour. My brake pedal went all the way to the floor and two of my dash lights illuminated (t/c (traction control), and brake light, also had the readout "service brake system". Luckily, I was rolling to a stop in my own driveway and avoided hitting my other parked cars. I inspected the brake system and found that brake fluid was leaking between the abs unit and the driver side rear tire (more specifically near the fuel tank) from the metal brake line. The brake reservoir was half full of brake fluid and completely drained within ten minutes of just sitting in my driveway . I inspected from what I could see concerning the underside metal brake lines; all brake lines are rusted and brittle and will need replaced.

While approaching exit ramp in delaware (exit 1a) traffic slowed so I began to hit my brakes to slow and all of a sudden the brake pedal hit the floor and I could not stop I almost hit the vehicle in front of me with the exception of fast maneuvering of which my dash cam caught, I swerved to the left lane to avoid a collision then hit the emergency brakes and got back into the off ramp then I realized that there was no break pressure and smoke bellowing from under the hood of my vehicle I pulled over to inspect and notice brake fluid leaking. I took the vehicle to national tire and battery where they informed me that I had a double front brake line rupture - I am having them replace (a $1000 job) however I've asked to retain the brake lines as proof.
