GAS.455 is right- it's pretty straight forward making up rigid brake lines. i bought a flaring tool aswell as used to make brake lines for small aircraft. if you flare it right and it doesn't leak during the first bleed then you can be confident it will be trouble free for years. i'd recommend using rigid lines as much as possible and flex lines only where needed ie one at each corner. i just replaced my vette's flex lines as they had swollen and restricted the flow internally so led to uneven braking. i used std ones thru Classic Chev. Braided lines look great (if you can see them!) and due to less expansion under pressure give a slightly firmer pedal but as VO said, they have to be made by an approved manufacturer. Guys at Ansett, when i worked there, had the hose shop make them braided lines for their cars and although they were made to handle 3,000psi and tested to 5,000psi they were defected...
