you need this tool (sorry for the large pic).
basically the center hex will push the metal ball out...you then turn the large hex and it will put a bead/groove on the tube.
it's about 30-40 bucks for each size...assuming they have the size 5/16.

the bead form tool (bead form I) i have and it's great for ICs and etc...but it's too big for your 5/16 tubing.
the 45 flare is ok..but it's a ISO flare...so it bends out and pretty much folds over. that's what's on the stock brake lines. you must use a quality tool and tubing here or else it'll leak.
37 flare is used for AN plumbing.
any questions?
