It's been said umpteen times before, but seems to bear repeating.......those "three-armed" pullers, since they pull quite some distance OUTBOARD from the center of the hub (the tapered fit at CENTER of the hub on the axle is what secures the drum in place), is a perfect, proven method to bend and ruin the hub's flange. You bend that flange and you might as well throw that drum in the trash. The KR Wilson-type pullers (like below) are the only safe (and sure-fire) way to remove a "stuck" drum. DD
