As of now I've been working on getting the brakes functional and safe so that the car is able to be putted around if needed in between projects. All was going good, until I went to disconnect the fitting at the brake hoses (which were dry rotted of course), and 2 of them ended up being rounded off and seized to which I had to resort to using a pair of Vice Grips to remove the hoses. I was expecting to have to replace the brakes lines anyway, but at this point should I only worry about the damaged lines or should I replace all of them?
