My wifes little reliable K reg. AX has the brake drum seized on rear nearside wheel,not sure why but i'm guessing shoes have become welded to it. Problem is now removing it,i've tried whacking edges of drum with club hammer but to no avail,i've loosened off handbrake cable as far as it will go,but drum will still not turn. Does drum come off without removing bearings or should i take castle nut etc.off. Any help would be greatly appreciated. Many thanks Brian
