One way to save money is to replace only the front brake hose. The main issue with the front brake hose, IMO, is that it balloons under hard application which reduces the hydraulic pressure/braking which can be achieved. That's why I ask people who are questioning installing a braided hose whether they are able to pull the front brake lever tight to the grip. If not, then replacing the stock hose may not benefit because not all master cylinder stroke/pressure is being achieved. Since the rear brake can be readily locked up regardless of the hose, the change is really bling although we often go to great lengths to justify. ;-)
I have not installed three piece hoses but well made ones will produce the same effect as a one piece. One possible issue might be that more connections provide more areas for errant air bubbles to stay which might increase the bleeding problems but since these can ultimately be cleared by tapping the hose, and/or bungee cord and dissolving, not a big deal. IME, hoses often fail at the ends so 3 times as many connections may increase that risk by 3 times, however 3 times zero is still zero so I'd not be concerned.
I'm not understanding "Aside from the obvious unscrewing of either ends while under emergency braking". Why do you think that unscrewing is even possible?
Hydraulic fittings don't unscrew under pressure, IME, even to the point where there is mechanical failure.
