Discussion
Another old chestnut revisited! As always - two schools of thought.
This is mine: The hydraulic pressure produced in a braking system is quite high. High enough for the fluid to expand the rubber flexible lines. When it does this, it produces that spongy feel caused by the pedal travelling further than it would if the hoses did not expand.
I have had other people tell me it does not make any difference. In that case why don't racing cars and bikes use rubber hoses? They're far cheaper after all? The simple answer is that in racing you can't afford to have brake lag, it wastes time. The transfer of brake effort from the pedal to the pad needs to happen as quickly and firmly as possible and that means you can't afford to have the fluid expanding into the rubber hoses. The steel braided lines reduce this expansion giving a harder pedal and quicker response.
The other school will argue, quite rightly, that ultimately the braking pressure/force will be the same.
I've had this discussion with a notable supplier of parts and service to the marque, having had the big brakes fitted. I asked about the availability of braided lines as many people down under had complained of spongy pedals. He said it would be fine and I should try the brakes in his demo car. Demo car was great with a nice stiff pedal. Mine wasn't. Turns out that said gentleman found out later that the demo had been fitted with braided steel hoses.
Quad Erat Demonstrandum!
BTW no complaints from me intended here, as with many things, it's down to a matter of personal taste and focus. Each to his own.

With my road bikes, I've typically changed from the standard rubber to black braided hoses. The way I view it when new, the rubber lines should offer same performance as braided, but over time as the rubber gets older its more prone to stretching under pressure. Therefore at some point it'll be worth changing to braided to get a more consistent feel, especially under extended high speed use, so worth doing when a natural opportunity presents itself or just because you have some money burning your pocket!!

Certainly available from the US.

Will be getting a set myself come AP day (soon hopefully). Personal experience is braided lines offer a better pedal feeling. Both with brakes and clutch.
