brake line (hard line) size considerations?

14 bolt and KP60 with 42's. Using a scout 2 master and booster and getting ready to plumb front to back. Of course braided from the drops to calipers, But trying to decide what hard line size? I'm doing stainless and already have a roll of 3/16 and some how a roll of 5/16,Thought maybe I'de order 1/4 run the same front and rear. Don't remember front being larger for any reason. What say you guy's?

I'm running a similar setup 14b/KP Dana 60/40's with discs front and back. Noticed IH put different size lines, but went with 3/16" CuNi for both and seems to work fine. Previous owner put an Astro hydro-boost and master cylinder in which seems to need more pedal travel than i'd like, probably due to the Astro having rear drums and smaller calipers. I might eventually put a master cylinder in from a 2500 to bring it in.

I ran all 3/16" on mine. D60/14B disc/disc with 1970 Corvette MC.

Typically disc brakes run 3/16" and drums run 1/4".

The Cunifer/copper-nickel/CuNi brake line is more expensive, but won't rust, bends and flares easy.

Stainless is a bitch, get a roll of 3/16" CuNi. It's a little spendy but it's better than conventional steel and stainless steel in every way.

Well I ran the 3/16 stainless I had. Ran the front line. I was actually impressed with it. bent and flared easily.Guess if using the right tools,It's not bad. Just need to order another roll to run the back. This is all on my 800 build, which I will update shortly. Made a lot of progress in the last 3 weeks after a LONG time tucked away.

Is this the stuff with a sort of dark green jacket on it? Protective coating if you will? If so,That's what I used on my 78.

Are used to work with Russell performance, and I never saw convincing reason to go above 3/16 or #3 hose. More capacity leads to spongeier brakes.

No. That's just coated steel. The green coated stuff you get at Oreilly is Edelmann RhinoHide. A 25' roll is about $25.

Cunifer is one common name brand http://www.cunifer.com/

You can get the copper nickel at O'Reilly under the Edelmann Copperhead brand (might Have to order it not all stores carry it in stock) A 25' roll is about $50.

3300CN 25' roll

Mostly correcr.

Gms ran 1/4 from prop valve to t on rear axle, t to drum was all 3/16.

Cant say as lto all makes, but ive yet see a light truck or car, disc or drum, with anything other than 3/16 at the brake assembly
