Hmmmm    I have manual discs on my Hornet and I have a slight vibration when I hit the pedal hard. So I think Theyre warped again. I had them turned right after I bought it 8 years ago, but I m not sure if I can get them turned again. I think I ll just go with new rotors if I can find them. Plus I think the back drums are getting thin. 
I'll look into it this spring . Right now my main concern is my radiator. I found a kinda new one on Ebay I cant wait to install. It is a litttle one, but It will work until I can get the big one recored.

Maybe I am just an old fart but I will take the power versus non power brakes any day. I drove my friends 79 Concord sedan with non power brakes. After I parted the car out a few years later I installed the Concord rear with it's larger rear drum brakes and the front discs! in my 7 4 Hornet. What a difference even though I used the stock 74 drum brake master and booster. I did add an adjustable proportioning valve though. This is about as direct comparison of power versus non power as you can get. Give me power any day.
