G-356 C-3,974 BLIND ASSEMBLY OF PARKING BRAKE CABLE TO PARKING-BRAKE LEVER ABSTRACT OF THE DISCLOSURE: A drum brake assembly having a parking brake actuating lever is so arranged that the parking brake cable end may be assembled in a blind fashion to the end of the actuating lever. The cable is provided with an enlarged end or button. The cable and spring are inserted through a guide tube and pushed inwardly into the brake assembly with the guide tube or a combination of the guide tube in a separate spring guide placing the cable button in a alignment so that it is aimed at a funnel-like guide and retention member formed on the end of the parking brake actuating lever. Further axial movement of the parking brake cable and its enlarged end result in a camming action which moves the enlarged end upwardly through and beyond the slot after which it snaps back downwardly to be positioned to be able to apply cable tension forces to the parking brake actuating lever. The entire assembly may be made with the brake assembly in the completely assembled condition wherein the drum covers the brake mechanism so that the assembler, operator cannot either see or manipulate that cable end and the connection thereof with the end of the actuating lever. The arrangement also provides for sealing the opening in the drum brake backing plate through which the parking brake cable extends, and permits checking for full connection of the parking brake cable with the actuating lever before such assembly is completed.
