ABSTRACT:
A drum brake in which a parking brake is incorporated. A parking brake lever is mounted in the interior of a vehicle and is operable to pull a parking lever through a cable. The rotation of the parking lever causes a pair of brake shoes to be forced tightly against a brake drum. This results in the generation of a braking force. A stopper member is provided to limit the maximum angular position of the parking brake. This design prevents contact of the parking lever with a rotary shaft due to excessive pulling of the parking lever and thus damage of the rotary shaft as well as the parking lever.
