Ultimately, the answer is yes. And they look cool (if you ever get under your cars). You will not have to replace them for the life of the car (or close to it). It will reduce brake fade, as most of it is in the rubberised lines heating up and going soft. Then when you hit the picks, the pressure increases and the rubber lines bulge, so you lose braking efficiency.
It is a bit like fitting a strut brace, a waste of time, if lots of other factors are not taken into account. You will get a performance increase, but not as much as possible. No disrespect to anyone who has, I'd love one. If a strut brace is not a solid unit, then it isn't really doing it's job properly. Adjustable for length is fine, but if it has hinging, it is not really a structural member of the car. (sorry about that aside!)
