This might end up starting a holy war, but here we go. (EDIT: I had the flare degrees backwards, but leaving it in for posterity)
I'm redoing the entire brake system on my 70 FJ40. I've already secured front disks, dual loop master cylinder, nicop 3/16 lines and a booster and now I'm looking at what to do for hard line fittings. For the flex lines, I'm going to use 3AN PTFE stainless with 45 degree single flares. But what about the hard lines? I can find as many posts saying I must do 37 double flares as I can saying to stick with 45 single flare and AN fittings, so I'm looking to muddy the waters even further and ask for opinions/experience here.
So how about it? 3AN everywhere? A mix of 3AN and double flare? through caution to the wind and just flex line the whole machine?
