The brake lines are 3/16", the fittings are metric a 131 mm wrench to get them off. These lines use a bubble flare, so pre-flared lines are the way to go. Also there are fittings available that switch from the metric bubble flare to the more familiar 45 double flare, if you just need to replace a section of the line.
You do not need tape on any flared fitting, brake or regular. The brake line and the fittings are different size and thread type than regular copper line and fittings. You can't mix them.

To do it yourself, 30 or 40 bucks, for someone else to do it 2-3 hundred. Its all about the labor, brake lines and fittings are cheap, but that job takes time to do.
If you have a power brake booster then there will be a vaccum line that runs to the brake booster on the firewall from the carburator. Check the booster for holes and broken fittings or buy a new booster. if no brake booster then brakes shouldn't affect vaccum
Much to my surprise, my Escape's (04) brake fasteners were all metric. I have both English and metric tools, used the English first cause it's a Ford and found they didn't fit. Went to metric and viola! I guess we can thank Mazda's influence for that.
