The correct pipe for brakes is available by the metre at all brake places, dont remember the cost but its not too dear. It is a composite metal material. You will need to double flare all fittings, they will do it for you but the tool is not ovally dear, I double flare all my fittings, fuel and brake. To bend them most can be set gently by hand but for tight radius bends I use a refrigeration pipe bender. These also are not expensive and achieve a high quality bend. You may have to do it a couple of times till you get the feel of it. After making the pipes for that nice "shiny" look I sent them off to be zinced. Not for the purists though !!,
