A drum brake assembly (10) having a parking brake actuating lever (64) which is so arranged that the parking brake cable (76) end (88) may be assembled in a blind fashion to the end of the actuating lever. The cable is provided with an enlarged end or button (90). The cable and spring (82) are inserted through a tube guide (92) and pushed inwardly into the brake assembly with the tube guide or a combination of the guide tube in a separate spring guide (98) placing the button in an alignment so that it is aimed at a funnel-like guide and retention member (106) formed on the end (72) of the parking brake actuating lever. Further axial movement of the cable and its enlarged end result in a camming action which moves the enlarged end upwardly through and beyond a slot in the guide and retention member 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 (12) covers the brake mechanism so that the operator cannot either see or manipulate that cable end and the connection thereof with the end of the parking brake actuating lever. The arrangement may also provide for sealing the opening in the backing plate (16) through which the cable extends, and permits checking for full connection of the parking brake cable with the parking brake actuating lever before such assembly is completed. |
