Im fairly sure the originals are 3/16" Bundy tubing, with metric threads on the flare nuts, and the usual 'double flare'. When I was buying the new brake lines (for our 92 LX), I found that the metric and SAE threads were really Very similar, and the auto parts place didnt have the different thread types sorted out. It was vital to read what the sticker on the part said, not just go by the tubing it was hanging next to on the display rack or what the counterman handed me! I always had a 3/16" metric threaded 'coupler' with me to make sure I got the correct item.
I replaced mine last autumn on our 92 LX wagon. Since there was only rust on the parts toward the back, I made a joint in the lines more or less under the driver's seat and cut the lines at that point. I bought the tool for making double flares, bought a few different lengths of the brake line (Bundy tubing) with the flares/flare-nuts preformed on the ends, and 3 or 4 couplers to screw together the lengths of shorter tubing. (There was no tubing in a standard preformed length that would have been long enough to do the job with a single length).
That way I only had to make a total of 4 flares myself, two on the old brake line ends, and 2 where I needed to shorten the new tubing to meet up with them. Because of rust I also replaced the lines running from the wheel cylinders & along the rear axle to the rubber hoses, replaced the rubber hoses, and the lines from the hoses on the underbody forward. I had long since replaced the rear wheel cylinders.
I dropped the fuel tank to make it easier to fit the lines up against the body as they were originally, and for two other reasons: 1. Because the car had 200k on it - I figured it had earned a new fuel pump. 2. Because the large rubber hose connecting the fuel filler neck to the tank had a split in the side. My two other Escorts also have a tiny split 'starting' on that rubber hose, so I judge its a common problem, & I will be replacing the other hoses soon.
If I were to do it again, I might try to run new lines all the way to the little block on the lower firewall where they start running to the back. At the time I didnt want to bother taking down the rock-shield that was covering up the lines that were that close to the engine compartment.
While I was under the car, I rubbed grease onto all area of the rear undercarriage that were rusty. That is now a maintenance item I plan to do a couple of times a year.
I would be glad if our Escorts would last another 20 years. I dont like the newer cars having ignition keys that have 'chips' in them that cost $40-$200 if you lose them. My Escorts all take $2 hardware store ignition key copies.
