So when I redid my car i installed the 2004 cobra front disc brakes and i also installed 8.8 with rear disc. I have a 2004 master as well. However whn i put it all together i used the factory hard lines to get the fluid to the ss flex lines.

I just installed the borgenson power steering conversion. when taking the car apart i realized that I could have done a better plumbing job. Also, i think the brakes should work without having to press so hard on the pedal.

So can anyone here direct me to some information one the best way to plumb it, what size hard line to use, and which distribution block is best. I did install a proportioning valve and all the corners work but i think i would get better performance if everything is re-plumbed.

thanks

How hard the pedal is will depend a lot on the pedal ratio. If the 04 Cobra has more leverage, you'll have a harder pedal, I think stock ratio on the Mustangs is only like 6 or 6.5:1

Sorry i dont really understand your reply. I am asking what size hard line i should use and whether or not i should be using a distribution block.
from what i read, i should not be using a distribution block. just a tee for the front two calipers and a single line with a prop. valve to the back two calipers.

You said you didn't think the brakes should be so hard to operate, that could be the ratio of the pedal. It determines the leverage you have to generate force on the m/c piston. For example, assume 1 sq. in. of piston area in the master cyl. and a pedal with a 10:1 ratio...if you push the pedal with 100lb of force you create 1,000lb at the m/c over 1sq. in. and produce 1,000psi of brake pressure. The same setup with a 5:1 ratio you only make 500psi for the same 100lbs of force at your foot.

If you had the wrong arrangement of pedal ratio, master cylinder etc, you could create a brake system that was impossible for a human being to operate.

If the m/c you're using was designed to use a booster, then you need to use a booster, since the area of the piston will be too large for you to operate manually.

As far as line/dist. block, standard brake line size is 3/16 iirc. A T works, or a dist. block that doesn't have crap in it (valving or whatever). Wilwood makes a proportioning valve/dist. block setup with isolated front/rear systems and the adjustment **** for the rear, and it comes with a pressure activated switch for the brake lights.
