ABSTRACT:
Herein disclosed is a cabling structure of a parking cable for a drum brake which is equipped with a backing plate, a brake shoe and a parking lever. A pulley is hinged in a swinging manner to the backing plate or the brake shoe and is formed with two arcuate grooves having different radii measured from the hinging axis. First and second cables are hung in the two arcuate grooves, respectively, and are connected to a brake actuating mechanism and the parking lever, respectively. The direction of leading out the parking cable can be different from that of the force for pulling the parking lever without any breakage of the parking cable. The pulley may alternatively be formed with one arcuate groove. Then, the second cable connected to the parking lever is retained on the pulley such that it extends to partially contact with the first cable.
