1975 Ford E150 problems (Dies when cold+no pressure in the brake pedal)

Soooo I've got 2 problems going on here, decided to work them in to 2 posts.

First problem is that after the car sits for more than 4 hours and the engine cools down, the idle becomes rough and will sometimes stall and die when driving. I've actually driven a mile and a half, then had the engine die in the middle of a turn.

Typically it dies right as I hit the gas pedal. If I give it TONS of gas, it's fine. If I let it idle, it will stay on. If I tap the gas pedal just slightly (as you would in many around town circumstances) the engine will die.

The problem goes away entirely once the engine reaches operating temps, and the idle seems fine when the engine is hot.

----------------------------

The other problem I'm having is with the brakes. If I press down slowly on the brake, there is no pressure. It will go all the way to the floor before it starts braking at all, and the brake light will come on.

If I press down quickly and hard, the brakes respond well, it will maintain pressure as long as I keep my foot down, and the brake light will go off.

I had meineke do a free brake inspection, and they told me everything looked fine, master cylinder's fine, and tried to tell me that adjusting the rear brake shoes would fix the problem well, I did let them adjust the rear brake shoes since I didn't really have the time to do it myself, and uh... surprise surprise, same issue.

So what's going on here? Bubbles? Leak in the vacuum line? I haven't tried bleeding the brakes and putting in new fluid yet, I guess that's my next planned move, but maybe someone out there knows a little more than me.
