That bracket holds the emergency brake cables, not the brake lines. Both the rear cable bracket and the ratio lever hang down but I've never had any issues with tearing them off. The ratio lever might be able to be removed and bypassed, as the 3/4 and 1 ton trucks normally do not have them, but they also use a completely different brake system so you may have issues pressing the pedal or getting full engagement. Anything more and you would probably be redesigning the entire parking brake cable system, which I had thought of many years ago and swapping to a floor pull lever, but it's never been an issue so I never bothered with it.
