History: i replaced the rear L-R brakes, calipers, and rotors. And front R- brakes, caliper, and rotor along with the bearings. L front brakes. After this work i began to bleed the brake system as usual pump and hod method while cracking the bleeder valve. didn't get a hard petal, it would slowly go to the floor. I started in the back and then the front when i was bleeding the brakes. So the next day i replaced the Master Cylinder and when i was removing the upper metal lines off the MC the rusty old line broke???? now i have to get a replacement for the two MC lines that go to the brake system distributor??? its hard to find a shop that can replaced these? i called the dealer and they do carry it anymore?
