Disclosed is an electronic parking brake. The electronic parking brake is provided with an operating lever, which is configured to support first and second brake shoes, which are installed at both sides inside a drum, and push the first and second brake shoes toward an inner surface of the drum when a pivot lever is pulled, and is electronically activated to operate the pivot lever to brake the drum, and the electronic parking brake includes a housing mounted on a vehicle body; an actuator installed at the housing and configured to generate a driving force for braking; a power conversion unit having a nut member configured to be rotated by receiving the driving force from the actuator, and a spindle member screw-coupled to the nut member to allow a rectilinear movement; and a parking cable configured to move according to a reciprocal linear movement of the spindle member, operate the parking brake, release an operation of the parking brake, and be connected to an end of one side of the spindle member, wherein the parking cable has a predetermined length and is formed with a single integrated type steel bar body to prevent occurrence of a bending deformation.

A drum brake assembly includes a brake spider having a central aperture configured to receive an axle extending therethrough and first and second brake shoes. Each of the first and second brakes shoes has a first end pivotally coupled to the brake spider. First and second cam followers are disposed at corresponding second ends of the first and second brake shoes. A camshaft has a shaft extending through a camshaft aperture in the brake spider and disposed along a rotational axis and a cam disposed at a first end of the shaft and in engagement with the first and second cam followers. An electric motor has an output shaft coupled to the camshaft. A controller is configured to drive the electric motor to cause rotation of the camshaft and move the first and second brake shoes between positions of engagement and disengagement with an associated braking surface.

A brake assembly having a brake spider that may receive an anchor pin or a sleeve that receives an anchor pin. Features such as splines may be provided with the anchor pin to help secure the anchor pin to the brake spider or the sleeve. Engagement features may be provided with the sleeve to help secure the sleeve to the brake spider.
