Buick Century had a brake fluid leak about half-way down from the fluid reservoir. To see the leak, a mirror on the end of an adjustable rod is needed.
Mechanic said he would replace 2 brake lines and the fee would be $300. While he was working on the car, he told me that a third line broke and I would have to pay another $50. In other words, 3 lines were replaced for $350, but I am certain that there was but one leak. Do you believe that the third line broke? If the third line really broke, am I responsible? Please comment.
