Last car I built had braided hoses through out, not one piece of copper or rubber pipe. You have to make sure it's protected as it acts like a saw and WILL make it's way through most things...
Buy the hose by the mtr then buy fittings as you need them, easier to make up than all that faffing about with flaring tools as it's a nut and an olive, if it leaks nip it up.....simples. On evey single bike with discs the first thing I changed were the brake lines as don't trust the rubber stuff as it pumps up prior to braking force applied, braided gives you firmer brakes and being able to stop is far better than all that 100's of BHP nonsense
