Ok guys during my upper and lower contorl arm install (hell of a job by yourself) I managed to remove the top layer of rubber on the rubber break line that runs from the underbody to the top of the punkin, then branches off via hardlines to the left and right drums. There seems to be a fiberous layer beneath the rubber coating and I did not seem to have penetrated the fiberous layer...there is no leaking or signs that I have breached the line. My question is should I replace the line, or will it hold up..I'm not familiar with the pressure this line experiences, and don't know how strong it is.
