  • Publication number: 20010017245
    Abstract: A brake cable connector device used for a brake device, and serving for guiding a brake cable into engagement with a brake lever when an end portion of the brake cable is introduced through an opening formed through a backing plate into the interior of the brake device under assembling. The brake cable connector device includes a guide member which is formed separately from the brake lever and which is fixedly attachable to the brake lever. The guide member is configured such that an end of the brake cable is brought into contact with the guide member and guided into engagement with an engaging portion of the brake lever when the end portion of the brake cable is introduced into the interior of the brake device at a predetermined position of the brake device. The brake cable connector device includes a guide pipe which extends through the backing plate so that the brake cable is introduced through the guide pipe into the interior of the brake device.
