Managed to get the RR caliper off the car, along with the broken hard line. Getting the tube nut out of the proportion valve body was a chore. Moderate heat a few times, then shock cooling with CRC "Freeze-Off." Even then I had to cut the line to be able to turn the tube nut, which finally came out with vice grips and destroying the flats. And this was after a couple days of soaking in penetrating oil. Just worked the nut back and force slightly while advancing.
Now, for replacing the hard line. NAPA has hard lines with bubble flares on each end, but with 3/8" tube nuts, which are almost 10mm but not quite. I need a 36" length, but the next avail size is 40". Looks like I'm going to have to get a couple of 10mm tube nuts and take it to a machine shop to bubble flare it. I can't find a tool locally to do a bubble.
I got a double flare kit from NAPA thinking I would just splice in a section, but the NAPA tool had a defective die with an oblong recess and would not make a symmetrical flare. Went to exchange it and all the rest of the stock had the same defect.
This is turning into something a lot harder than it should be.
