The original inspection may have found a legitimate fault with the brake lines. My 1982 Chevy Van had only one wheel braking (Yeah. Suspence!). Road salts, etc, had rusted the brake lines through. I took the old brake lines off. Straightened them out, went to the auto parts store, and got pre-cut, pre-flared, pre-couplered brake lines off the rack, which were within a couple of inches, in length, of the originals. Put them on easily (no finite calculus involved). The van, then stopped, when I said, “Whoa, Nellie!”! // My question is, “$300 dollars for a cut-and-splice”? Why cobble up the lines, even if the joint couplers are acceptable?
