I was refering to "Aircraft quality stainless steel brake lines, improves brake pedal firmness and resists pedal fade" found at http://www.msdsinc.com/vanagon_btb.htm thats a part of http://www.msdsinc.com/ Dont know what to think of their vented brakes versus the SA bigger brakes... only I guess the SA is only good for 15 inch wheels... and I might get 15 inch, or I might not.... Thanks for your informative post. I saw cryogenic discs in an ad once, didn't know what to make of it.... >From: Gary Stearns <gstearns@SPRINTMAIL.COM> > >Are you referring to braided stainless bake hoses?
