Default Braided brake lines

I want to run braided brake lines from my master cylinder to a junction in my brake line. The braided lines would be about 12 inches. Is this legal for stock or is this just a bad idea? Thanks Brett

The "rule" I learned many years ago was to use as little braided brake line as possible (and therefore, as much steel line as possible). The theory (as it was explained to me) is that braided line still "expands" internally, when pressure is applied, which tends to make the brakes feel spongier.

Incorrect and misinformation unless you are using some cheap Chinese braided steel brake lines.
If you utilize steel braided brake lines that meet the DOT FMVSS-571.106 requirements, there should not be any problems.

Russel and Goodridge sell steel braided lines that meet and exceed the specification.
For additional safety, go to a hydraulic shop that can crimp the ends.

Not entirely corrrect. The research I've done says that the only braided line that should be used is the Teflon-lined stuff. The non-lined lines, DO flex. And though I looked extensively, I found no one who recommends making the entire brake system out of braided line, probably due to expense. By the way, are you ever going to expound on my erroneous information on cryogenic treatment?

Oh, I forgot. DOT FMVSS 571 specifies testing requirements for brake hoses that I would wager no fabricated-to-length braided line could pass. The testing requirments are extensive and assume the complete hose/line assembly can pass,

Heck, if 12" was all I had to deal with I might consider it myself. Russell has them in many configurations from 9" to 27" in length. http://www.russellperformance.com/mc...niversal.shtml

I will when I have time; I just try to give the brief version of things in lieu of the thesis oriented versions.
Been too busy on the road; as a matter of fact, I am responding to you from 38.000 feet of altitude.

Good. Based on your comments, I decided to do nothing with the crank and valve springs on this freshen-up. If the info I've collected is inaccurate, I'd like clarification. Not so concerned about the cost as the benefit, so doing it right matters.
