Abstract
A drum brake includes a spider having an anchor with as-cast recesses and anchor seats machined within the as-cast recesses. The as-cast recesses provide clearance for a shaft of a cutting tool during machining of the anchor seats. First and second brake shoes are pivotally supported by the anchor. Each brake shoe has a convex web portion positioned in communication with one of the anchor seats to transfer braking loads to the spider.
