So I am cleaning up the area under the coach, in preparation of installing the freshened fuel tanks, wiping things down when I wiped a brake line...and then it starts oozing fluid:

I know I should be thankful it happened in the driveway and not on the road, but I seethed at the new hell this wicked mistress thrust upon me...
So after a few adult beverages and some quiet reflection I chose to soldier on. Those of you who saw my photo of the new combo valve the local shop installed probably cringed at what they did to the hard lines:

So I kind of knew the lines needed to be replaced at some point.
I went with Polyarmor. I replicated what I had in the coach, which may or may not have been original. They were crusty enough to be 38 years old, and other than the combo valve fiasco looked to be unmolested. The run from the combo to the rear T used two 60" pre-made sticks of 1/4" and one 40". I used the 40 up front, and trimmed it to fit since it needed a 1/2-20 to connect to the rear of the Combo. This seemed to be close to the original config.
The lines to the MC were over 60" long, so I had to use rolls 0f 1/4 and 3/16. The 1/4" line was connected to the front MC port with a 1/2-20 fitting, and to the rear top of the combo Valve with a 7/16 fitting. The 3/16 was connected to the rear port of the MC and to the front port of the combo with 1/2-20's on both ends. Does this sound right? Coach was stopping on a dime and giving change when it ran last.
As usual, a thread like this is useless without pics so here we go:

And a partial set of brake lines - only slightly leaky, used once...

Driver side combo to brake I used a 20" 3/16 pre-made line - I hate flaring lines.
Just have the rear two and the run to the passenger side left...

Abbra kadabra - poof, you are a brake line... 
Master cylinder and booster changed as part of initial rehab when I first brought it home. Almost mated with a new Honda @ 25 mph on the test drive - had to stand up behind the wheel to stop the coach. Those in Law Enforcement would call that a clue... those of us addicted to old cars call it a cry for help. Still haven't figured out if it's me, or the vehicle, crying for help.
Eventually I will run out of things to replace...or money...

Joe,
Much better job! Can't tell from the photos but if you haven't tied the lines from the M/C together or to the frame it might be a good idea to do so.

Working on it. The local shop left the line clamps in the engine compartment on the shop floor, so I am making it up as I go, but it seems the lined were bolted to the top of the frame rail forward of the shock mount, and to the side oft he radiator support, along with the oil dipstick tube? Looking for the thread pitch of the bolt that uses the pre threaded hole on top of the frame.
