  • Brake cable connecting apparatus for a drum brake device
    Patent number: 6962241
    Abstract: A cable disengagement prevention configuration for a drum brake device that provides a simple and safe connection of a brake cable to a brake lever and reliably prevents disengagement of the brake cable after connecting the brake cable to the brake lever. The cable disengagement prevention configuration mainly comprises a bowfront portion (18f) of the brake lever (18) and a brake shoe (11). The bowfront portion (18f) is formed between a primary seating (18e) and a secondary seating (18g) and is positioned apart from the primary seating (18e) at an opening side of a U-shaped groove (18d). The cable disengagement prevention configuration allows a cable end fitting (28) to pass through a gap between the brake lever (18) and the brake shoe (11) only when rotating the brake lever (18).
