Braided SS vs. Hard Line

My opinion only......
Any time you can replace rubber (which is what most braided stainless line is) with hard line, I do it! I'm in the process of changing 15ft of braided rubber fuel line that leaks like a sieve with hard line.
IF you decide to use flexible line, you MUST use teflon line for brakes. And all the special connectors that teflon requires, along with specialized assembly techniques.

Thank you for your thoughts! I will have to research more on teflon lines as I'm not familiar.

One of the biggest concerns I've read is that the braided lines allow for some expansion, creating a softer pedal and more travel before the brakes engage compared to hard lines.

I have also read some product info on braided lines from manufacturers that claim to have resolved the expansion problem. I don't have the knowledge, unfortunately, to assess such a claim, and I appreciate the feedback.

I have access to some SS braided brake lines on the cheap, and if feasible (safe), thought it may be worth the convenience to replace the short hard line on the drivers side rear at least.
