Losen the rear brake adjuster. Remove the rear right wheel, axle nut, hub and there are like 6-8, (dont remember) 8mm bolts on the drum cover. take those out and there are two slots between the brake cover and backing plate. Using a screwdriver insert and twist. The cover should pop off if its not full of water and rust. after the cover is off, slid the drum off the axle and you are looking at the brake pads.
