What are the benefits of braided/stainless steel brake lines?

Higher pressure rating, typically 3000psi operating – 12000psi burst. i.e. this may be very important at solving the problem of the stock rubber brake line failures.

Stainless-steel armor-like outer braid PTFE-lined fluid transport inner tube, resistant to brake fluid, and high temperatures. Will not crack like rubber hose lines.

Better “brake feel” because there is significantly less hose expansion compared to rubber hose lines, there is more of a direct correlation to pedal pressure to braking pressure hence better “feel”.
