Unhappy Front Brakes Dragging

So I cleaned the calipers and all pistons are moving freeley by hand.
New fluid, pins are clean and lubed , front axle nut is @ 40 ft./lbs., pinch bolts after bouncing forks with the wheel on the ground @ 20 ft./lbs.

put my used hrc soft bites in and the wheel is hard to rotate and rotors make a grinding sound ( it is on a handystand and I wonder if that moved the pinch )

I can't even get a full turn and had to leave for work this morning bikeless

Any Ideas fellas

Where you able to check your rotors to be true? Warped maybe? High spots can cause pads to drag. Can u tell which side caliper is dragging best way is to take the one caliper of and eliminate that way.

Is your master cylinder overfilled?
You said you reinstalled the used pads, so I wouldn't ordinarily expect it to be.
Axle spacers on the correct sides?

Thanks for the responces, rotors are true,spacers are correct and fluid is not overfilled.
It's rain in the forecast today and I think tonight I will put it up on the triplestand and reset the pinch using the spin and brake method then report back.
This set has a pebble gouge on one pad and mebbie needs a file taken to it ?

(grasping at straws)

Before the wheel install did you check wheel bearings? Grasping also...

No I didn't, but they are marchis and 40 /lbs is what I have always used on the axel.

Ok I used to work at a bike wrecker eons ago...we would have to push the bikes in and out and for the most part it was straight forward. On occasion we would get bikes that didn't push so easily, so what we did was smack the calipers with a dead blow hammer and that would fix the brake drag issue temporarily.

Try it if it the wheel spins freely from there then you still have a braking issue...if not then it's either a problem with the install, bearings, fork height or the spacer in between the bearings? Grasping still...

Take it for a ride, then see what it does. I think you are just over analyzing it.
