drilling out lugs from hub, disc brake upgrade

If You're not savin' the studs or drums, a 7" grinder w/a wafer-wheel will eat right thru the swaged jobs, then pop 'em w/a punch/air chisel.

Same here, cut them off from the front side, hit with a little 3' grinder, and a little tap and they fall out. Should be swedged back in, you don't want the whole works spinning in a hole with the wheel on it when your on the side of the road. I have tacked them in place.
