4. Unscrew the nut, remove the nut retainer, thrust washer and remove the hub (brake drum) by pulling it towards you.
5. Remove the front brake shoe mount by using pliers to press the spring cup against the brake shoe and in this position, holding the strut behind the brake shield, turn the cup 90°, remove the cup, spring and retaining strut.
