[DeTomaso] Stainless V Non-stainless brake lines

[jderyke at aol.com]

Stainless is harder to bend than mild steel and is maybe 3X as expensive. But because it work-hardens ahead of the flair producing tools, its been found that one only needs to single-flair stainless tubing, making it a bit simpler to work with in that respect. Double flairing usually cracks the overworked ss lines. FWIW,  double flairing began because hydraulic brakes in the late '30s used 'Bundyweld' lines. This is a copper plated mild steel sheet rolled into a double wall cylinder and heat-brazed into a tube. Without double flairing, the tubes often cracked at the braze line.

  I'll be running new brake lines for 6328 when I go to put her back
  together and I'm debating whether to go to stainless brake lines or
  stay with the regular steel lines.  I know stainless is much more
  difficult to work with but won't rust.  I did not find any noticeable
  rust on my old lines that came on the car so doubt replacing them with
  new regular steel lines would result in a problem, and would be much
  easier to bend and flare.  I do plan to do the work myself.


  Thanks
