Ok so I want to replace all my lines and since Classic Industries messed up my order sent me the wrong line (fittings anyway) and after I install I realize this and break a new line in a billion pieces in my fit of rage. Yes i know retarded move for a $150 piece and I hate taking my stuff to shops when i can fix it relatively cheap. Would it make since to run all braided line... I know everyone says not to, that it will be spongy. But earl's speed flex line is rated to 2k lbs of pressure I wouldnt think brake lines would make that much at all. I just want some pros to chime in and see what they think. Also any fitting sizes would just be amazing.

 

no, the pedal will be spongy. i dont care what the flex is rated for, its not a solid line, and it will expand, and make the pedal spongy.

brakes pressure is well over 1000psi, probably more to the fronts.

there is a reason its not done this way. Order the correct replacement lines, or buy a flaring tool, a pile of tubing and try it yourself.

 

Quick question. For left to right (mostly on the front) dont the hardlines to be the exact same length or can one be shorter than the other from left to right?

 

I've taken the lines off of a couple cars to replace them now, and I can tell you with certainty that none of the 4 lines are the same length in most cases (there's like a foot of line on the driver's front and 8 feet on the passenger's on a Plymouth Acclaim, for example, from the proportioning valve to each brake hose). As long as there is no air in the lines and equal fluid moves to all 4 wheels, there will be no problems.

:edit: And, OP, there is a guy on here who makes braided hoses for our cars and sells them in a store on eBay for about $80 a set. The rest needs to be solid, double-wall steel hose.

 

Since fluid doesn't compress (hydraulics theory), and assuming there is no air in the lines, you'll be applying the same pressure to each caliper's pistons when braking, no matter the length of the lines.

 

You can plumb the whole thing in stainless, but I only use braided hose where it needs to flex. You can get everything you need to do the whole thing that way from Summit for about $150, but you'll need to be able to flare stainless line, and most of their fittings and hoses are in Army Navy (AN) sizes, so you'll need a 37 degree flare tool. Far easier to do it with steel line, and cheaper, too. you can get 25 feet of steel line for $20 or so, stainless is twice that, and cheap flaring tools won't work stainless.

 

I had braided lines on my brakes and within 2 months they ripped and I lost all brake pressure. These were the same braided lines that came from bigbrakeupgrade.com.
I know of at least 3 others that failed also. I might have been unlucky I don't but, I will not use them again.
