Can i ask what you use to connect the hose ends? I thought some kind of industrial press was required in order to get a seal that will not fail under pressure???
Standard compression fittings, in short you remove the outer coating (if present) slip the nut on, spred the outer braid, trip the inner tube, fit the oilve onto the tube put the main fitting body on then tighten the nut over the olive onto the fitting body which basically crimps the olive onto the inner tube.
the fittings you are talking about ar the once that come on supplied kits and are more of less the same thing but not threaded and are crimped into place.
Once thing i would say is dont built it if you can buy it, a pre made hose kit will be a good bit cheaper than anything that you make up at home as the end fittings are expensive (about £5/6 each) so a 6 line kit would have about £70 worth of fittings on it before you buy any hose.
Most of my internal brake lines are in cunifer pipe which is much much cheaper, like about £12 for a roll and the fittings are pence.
Braided lines are also a bit of a concern if your going to be welding on the car, as apparently you can get an arc in the braid, never actually seen it happen, but its not something that would be good to find out about on track.
