1991 Chevy Caprice How to fix brake line

Those lines have to be made. The line will have to be cut further up the line where the line is in good shape and then a nut installed and the line double flared. New line will have to be bent to correct shape and double flared at every joint and then the system bled out. This is not a fun or easy job so if you've done done anything like this before, pay someone else to do it. A bad joint or leak could cause loss of brakes.
