Brake line size?

Ok next step I need to fab up some brake lines for the truck. Does anyone know what size lines I need. 67 C-10 SWB power brakes with 72 discs up front. I have no lines at all on the truck right now. Thanks all
Tim

Re: Brake line size?

Ok I think I figured out that the rear axle line needs to be 3/16th but do the rest of the lines need to be 1/4 or should they also be 3/16?

Re: Brake line size?

What master cylinder and prop valve are you going with?

I put all new '71 brake lines on my '68. I also used 71-72 master cyl. and prop. valve. By using the 71-72 master cyl & prop valve, the only differences were the way the lines mounted to the subframe and rear axle. 68 mounted to the rear of the crossmember, 72 mounts to the front of the crossmember. And on the rear, I just had to use a bolt instead of the original clip that was used to hold the junction block on....

If you are using the 67 master cyl and prop valve, I'm not really sure what to tell you, because they are very different than the 71-72 versions.

Hopefully this helps some????
