Any worry about copper-nickel brake lines on unsprung suspension components? On my Focus, I replaced a hard line to one of the rear wheel cylinders. The Focus has a trailing arm rear suspension so they use a flex line to the front of the trailing arm and then a 13" steel hard line down the arm to the wheel cylinder. The hard line has some bends but is only supported at each end by the fittings. Its a 3/16 line so it's not that heavy but its going to get a lot of vibration pounding down the road on the unsprung part of the suspension.
Copper-nickel line sure was nice to work with but that softness has me thinking about how much it might flex and its fatigue life.
