Was working on my 86 GT wheel well (driver side rear) when I noticed small droplets coming off a metal line covered with rubber hose (probably for protection against rubbing). When I went to touch it I realized it was rubber hose covering another rubber hose, connected to a metal line. These two metal lines run from the front of the car to the rear all along the drivers side. I tracked them up through the front plastic tire cover and it looks like they are going to the master cylinder. I thought brake hoses should not be connected to rubber hoses? I also forgot to mention that the metal lines look like they have small washers attached to the line every 1/8" apart.
Automatic transmission has two lines running to the back, on the driver's side. Brake line runs on the passenger side. The lines are metal, wrapped in a stone guard wire. They connect to rubber lines near the tranny. You can replace these lines with generic brake line material, or rubber transmission hoses, or a combination. Just flare the metal lines a little where you connect to rubber tranny lines.
BTW, if you get metal lines, get the coated lines (green), as you can bend them without a tool and they won't kink.
