question about steel braided brake lines
I've never done a brake line upgrade on any of my bikes.
Standard practice (and what it says in the manual) is to replace factory rubber lines after four years. Presumably this is because rubber gets hard and brittle with age. But what about aftermarket lines? No rubber, just teflon and steel braid. Would these be lifetime lines?

Quick look shows the teflon hose actually will last forever.
Only need to replace if the braiding is showing signs of weakness or damage.

Teflon is the bomb, and the braided stainless lines will not flex nearly as much as the OEM rubber.
the result is near zero maint required on the lines, and a 2 fold increase in "firm" feeling of the brakes when properly bled. this is a teflon line used as a supply to the MC... 10 years old and the same as the day installed.

The rubber lines don't last as long under constant UV light and heat not to mention constantly flexing and relaxing so the rubber eventually stiffens up and becomes brittle. I don't know why we haven't gone to non-rubber lines for everything else on the bike yet? Although a teflon core would not work with fuel lines, I'm sure we have something else kicking around that'll do the trick. |

I had a braided line fail on the oil cooler of my Harris. The bike is from the 80s and so I go with NOT forever.

Braided oil cooler hose is still rubber typically. it will fail and degrade just like regular rubber hose.

Rubber is much better at handling vibration, but it stretches more with pressure and isn't as armored in "road debris" situation. nothing is forever, but steel braid brake lines will last longer then the OEM rubber...

By the time my bike is 30 years old I'll be 82.  I can live with that.
