Try depressing the brake pedal lightly with the engine running. Does the pedal gradually drop with light constant pressure?
couple questions, why did you replace all those parts? and thats about it for now

bd do you think the old MC and new MC could have the same problem? i mean i know stuff can be bad right out of the box but couldnt the problem lay in the brake lines/hoses
...At any rate, I'm gonna do a complete re-inspection and check parking brake adjustment.I'll see how it is then.
one thing that im thinking is a hose is blistering causing the fluid to go to a hose bubble and not the the wheel cylinder or whatever
Checking the hoses while the petal is applies id a good suggestion.I have noticed that the rear brakes will lock up when sufficient pedal force is applied.I had not mentioned this earlier because until I replaced the shoes and drums, the shoes and drums had been contaminates with brake fluid or grease, which will cause the drum brakes to grab.So, new drums and shoes, adjusted (parking brake as well) and rear braking is balanced side to side,but still will lock up earlier than the discs in front.And the pedal still goes rather far down.With regard to m F150 brakes, when I applied them, I could feel braking occur, then subside.I do not experience this with the Chevy.Possibly a hose or hoses have some give which they should not.As the pedal is rock solid without engine vacuum, maybe manual only force is insufficient to cause a hose to swell, but vacuum assist may provide the force to do so.On to this step.......
