Most of the time with the problem you describe it turns out to be the brake hose they start coming apart on the inside and create a one way flapper valve, raise it up and have some one push the brake pedal while you spin the front wheels, they should spin free soon as the brake pedal is released, You'll find one hanging up probally the right front, when ya find the one hangin up simply open the bleeder and see if it releases the brake,if it does replace both front brake hoses, if it doesn't replace the calipers, calipers are cheap nowdays so we never rebuild em
and a side note if we replace the calipers it gets new hoses (cheap insurance)
