Brakes Dragging BAD

[blown240]

I was running errands and was thinking about how good my 61 was running. On the way home from my last errand my brakes started dragging. I was only about 3 miles from home, so I drive home very slowly so as not to over heat then and cause a fire.

Once I got home, I jacked it up and all 4 drums seem to be the same. Cant even start to turn by hand. Also the pedal has no throw, I can't even move it enough to turn on the taillights. Fluid level is good.

The entire brake system was replaced just a few months ago. Drums, shoes, wheel cylinders, master, booster, capt fab bracket, most of the hard lines, all the soft lines, and all the hardware is new. It has been working fine until today.

Any ideas? Im thinking something in the booster/master/linkage...
