Air-powered cutting wheel (and about an hours worth of hard wire wheeling) makes for quick, surgical cleanup of old brake hardware. To save time, and since I already figured out how to remove the axles, Decided to just block and wedge a screwdriver handle behind the axle flange this time for stud removal. So quick. Just pull out on the flange and wedge it. Old nuts and a 4 lb hammer takes about 3 seconds to drive them out.
