Brake Hoses, Lines/piping, And Fittings problems of the 2000 Chevrolet Tracker

I purchased the Tracker 6 days ago and the brake lines broke 5 days after purchase. I was driving home from work at 5pm on Thursday 8/17/17 and left one stop light to drive up a hill to another stop light. The brake lines broke while driving in third gear at 25mph as I was decreasing my speed to stop at the second light. My car should not have passed inspection but it did and my safety was in jeopardy every moment I drove thinking the car was safe to drive. The brake pads were worn down completely, so its metal on metal. The rotors are shot and rusted. The fuel lines and brakes lines are rusted, the transmission is leaking and the differential is also leaking. The car needs $1300 in repairs just to fix the break lines and replace the brake pads/rotors. I would not have purchased the car had I known that. Especially when I brought it to be inspected by an objective third party mechanic to inform me of any major issues and they told me nothing was wrong and that the car was safe to drive.
