brake line plumbing..help

Ok, I am new to setting up brakes. I am running a power brake booster on the firewall front MII IFS and a nova rear. I know there's a line that sits on the rear end and splits to each drum. and I know theres a line that goes to each front disk thats stops about a foot from the caliper.
questions
1. after using a metal hard line from the master cylinder do I go to a rubber hose and if so what size?

2. coming off the master cyl. hard line to the front brakes do I split this through a valve or how do I make this split to goto each disk.

Those are really the two things that are holding me up. Thanks.

I'm no brake expert but here's what I try to do.

Most people use braided steel flexible line from the frame to the calipers or drums. This stuff is available from almost any street rod shop or mail order house.

When it comes to the master cylinder it would be a good idea for safety purposes to use a dual reservoir master cylinder. With a dual reservoir system the larger reservoir would feed the front disks and the smaller reservoir would feed the rear drums. That said, make sure you get one that is matched to your brake setup. If you're running disks all the way around then you need a master cylinder designed for 4 wheel disks. If you're running disks up front and drums in the rear then you need the proper master cylinder for that setup. There can also be differences between master cylinders for power and non-power systems. For me, the easiest way to go is to try to use a master cylinder that was designed for the brakes you're using. Then you're pretty sure everything will be the correct size and will work well together.

thanks centerline....I guess I'll also pickup a line kit (or whatever it's called) in louisville. The kit should have all the tabs to weld on and lines for me to use.

You didn't say what kind of frame/car yer doin...here's a good looking way for the rears. If you're of a mind to do so, run hard lines to the back, tee'd off to get a flex line mount to each rear wheel. Use a nice braided flex line at each wheel and yer done. What's nice bout this is the rear axle is clean, no tabs or hard lines, and no flex hose from the frame to the axle. May help down the road for exhaust clearance and such too. Just a suggestion, hope yer project goes good.

brakes

You need a proportioning valve. You can use a stock one or an adjustable aftermarket one. Without it your back brakes are going to lock up on you.

I think you can replace the prop valve with residual valves. A #2 and a #10

2 totally seperate items. A proportioning valve will allow you to adjust how soon the rear brakes will lock up in Proportion to the front.
A residual valve is usually run when the master cylinder is mounted lower than the calipers(ie.frame mounted) That way you won't get a bleed-off back into the master cylinder.
Later,

WEIMER...you're right....don't know what I was thinking. There are different configurations and pieces, such as a combo valve, prop and resid, etc.
