Brakes

I have a 1984 Dodge 250 Power Wagon. I was driving home today and I had to stop at a light and when i took off again my brakes were still engaged and i could barely move. It eventually got back to normal but when i tried to stop again a mile or so down the road I had no brakes at all. I got it home and parked it for about 8 hours and I got back in it and it has brakes now but you have to push the pedal down a lot farther than normal for it to stop and it doesnt stop very good. Does this just need new brake pads or would it need new calipers or something. Or would it just need some brake fluid? I havent got to check the fluid yet because this thing has been sitting outside for about 6 months and it has a ton of wasps under the hood. Any help would be greatly appreciated.

 

Calipers could be partially rusted up OR you could have a bad brake hose. When a hose deteriorates inside the debris can act like a check valve and not allow the brakes to release. You will need to do some more investigative work.
