So I am debating on getting SS brakelines have not decided on what ones or even if it is the way to go. did a search found this post.

now I'm trying to break it down and understand a bit more on these.

first the reason you would want to change would be a more stable braking and peddle braking. This is due to the steel braids keeping the hose from flexing or bulging.

now after reading the other post it states that steel braids make it hard to see failure in the hose itself. failures which may be cause by the steel braids cutting into the hose or tiny particles caught between braids cutting into it.

there are many companys that put a sleeve over the braiding to avoid this problem.

but now this leads me to think about it in a more general basic physics form.

when pressure is added to an enclosure it is natural for the pressure to want to be released through an exit. if the pressure exceeds the rate of exit then the pressure will want to find another way out.

if there is no exit or the rate of exit is to low eventually the pressure will force an exit starting with bulging and eventually exploding the enclosure.

in theory
a regular rubber hose that expands gives leeway and expands to accept this higher pressure buying you some time. basically this expanding acts sort of like a relief valve.

now if the rubber hose is steel braided and the walls in general cannot flex you are going to have less volume. creating more pressure. now in this situation I see the pressure going two ways 1) the exits causing the hose to detach from the attachments on either ends.
2) the wall bubbling through the steel braids and the braids themselves cutting or popping these bubbles.

which leads me to my question for a modified street car is one better then the other

If I decide to go steel braided which would you recommend in fitting, quality strength at the attachment. and steel braids coated as well

I'm asking for your opinions on steel lines and my theory above is just a theory please feel free to correct me or take it further

thanks

I got some SS lines from rx7.com and would never turn back to rubber, I love them, high quality and PERFECT FITMENT.

Your reasoning about the hoses is flawed. Hoses are rated for various pressures. SS brake lines are rated for a higher pressure than you will get while braking. So they won't burst.

If I remember correctly brake lines(well most hydraulic lines) are vacuum tested to 3500 psi, and that is the minimum.

Why not look into goodridge, very well known brand, or go with a local hydraulic shop that is DOT approved for brake lines, if you have any problems they're a drive away.

i went with SS lines because they don't cost much at all, and i needed new lines anyways when i put in my rebuilt calipers and new everything (compared to the cost of those, SS lines were a bargain).

not too many people have problems with SS lines. they are usually covered to protect from dirt like you mentioned.
honestly i don't know if they make a difference in pedal feel or braking performance, but i still prefer them over rubber.

i got mine from corksport.com

i was looking into corksport since I'm getting a few other things from them how is the fit.
