How to Cap the Brakes Lines for Staging, Seems obvious how to, but not to me Options

[Highland]

So I'm at the stage where I'm going to drop the brakes and suspension to change bearings, bushings, calipers, rotors, pads, shocks, springs, etc. I plan to start with the rear then move to the front.

So the car will probably be off its wheels for some time while I'm trying to figure this all out.

I've emptied the brake reservoir with a turkey baster, but of course there's still fluid in the lines. I'm also thinking it would be easier to bleed the lines if there's fluid in them.

My question is where is the best place to disconnect the brake lines (before or after the flex) and what's the best way to cap it so I don't end up with brake fluid on my paint?

You don't need to replace the hard lines unless one is kinked or badly rusted.

As suggested above, move the pedal to 3/4 depressed so no fluid flows. Then cut the rear hoses close to where they clamp to the chassis and use a deep socket to grip the hex end instead of fighting with a flare nut or open end wrench in that confined space.
