Update
Kroil is not a miracle product
Adjusters still wouldn’t move
Thought I’d remove the tires getting ready to cut shoe hold down pins
My 3/4” Chicago pneumatic impact would not break lug nuts loose so had to heat them
After that wheel spun freely
No clue what happened
Better to be lucky than good
Just barely got drum off with ridge but got it off
Thanks again
With a 3/4 inch CP wrench, you ought to be able to dang near twist the bolts/studs. I use a 1/2" Ingersoll rated at 600 ft/lbs, but it won't give full torque until I remove the restrictive quick connect and attach the 3/8 hose directly to the wrench. Give that a try next time you really need the impact and torque. Torque spec for my Budd lugs/bolts is 500 ft/lb
