you can bend it by hand, don't make any sharp turns with it like tight 90's or 180's. get some extra since its cheep and play with it before you make your line. bend a little bit then move down the line 1/2 to an 1 and bend a little more untill you get the feel of what the line will do. i bend all my brake line by hand and never have a problem but if its real tight ( like real real tight 90's) then i may use a bender or a socket. just be sure not to kink the line, then your fucked and have to start all over.
