make a small kit with a jar/bottle and a thin clear flexible pipe, the pipe should go all the way down to the bottom of the bottle/jar - connect the jar to the brake bleed nipple, unscrew it half a turn and place the jar above the level of bleeder but below level of brake master cylinder in engine room.
fill brake fluid container in engine room to the top and now get into the car and slowly press the pedal only half way (do not stroke it to the floor) - pump it 7 or 8 times and refill the brake fluid in the engine room, check the setup you installed on wheel for clean brake fluid in the pipe from the bleed nipple. Repeat this for all wheels - never let the brake fluid container in engine room get empty.
The first wheel you bleed will take the longest as it will be flushing out the brake fluid container itself.
If your brake lining separated from the shoe backer plate then it probably was either a really bad quality brake shoe or your brakes were dragging (too tight) Wash the whole brake with soap and water before servicing it, if your new brake shoes have no coating for rust protection then you need to spray primer on them, Clean the whole system and make sure the auto adjuster is not jammed or siezed, free it up and lubricate the 6 points on the support plate on the brake where the shoe slides against.
