As pictured, take a long, skinny, straight-blade screwdriver and loop the left end of spring around the shank. Put the tip of the screwdriver into the hole in the brake shoe. Move screwdriver handle to left, stretching spring to left. Once the screwdriver over-centers past the left side of the hole in shoe, the spring end will slide down the screwdriver shank and into the hole. Pull screwdriver out of hole......done! DD
