jack up motor, support with stands,remove wheels,remove calipers and tie up to support hose,remove half shafts and hub lock and adjusting nuts,discs and hubs should pull off revealing the h/brake shoes,before you start this job it may be worthwhile having caliper overhaul kits available,caliper bridging bolts and slides are bad for seizing and also the h/brake adjusters too on the shoes,n/s and o/s turn different ways to adjust, sorry cant remember what way,rebuild in reverse paying careful attention to your hub adjustment,good luck
