'73 Swinger brake drag

There will be "some" drag. They will run "warm." But they should not be blistering hot. Jack up a wheel. How hard is it to turn? My memory is that they won't "spin" freely with disk brakes but if you give it a fair shove they might continue for 1/4, 1/2 turn but likely not much

One thing you might do is soon after you apply the brakes, AKA inside of a couple minutes, crack the fitting up at the master for the front brakes and see if there is any pressure
