brake lines on 1996 Chevrolet Lumina APV

im replacing a rear brake line. i cant tell which line to unhook from the master cylinder. is there a schematic that shows so i dont have to unhook them all?

You have to follow the line from the rear to the front to determine the correct line to disconnect.

You should try to run the line before disconnecting anything just zip tie the end that attaches to the master cyllinder to hold it until it is connected,you dont have to remove the old line if there is room ,just switch the lines into the holders gently and leave the old one zip tied in place if it would be hard to remove or possibly cause more damage to other brake lines.Hope this helps
