Abstract
A brake assembly is provided having a brake spider with a hole. An anchor pin is supported within the hole and includes end portions extending from the spider. The end portion has a first interlocking profile, which may be a recess or flat in the outer cylindrical surface of the anchor pin. The cylindrical surface extends preferably to the terminal ends of the pin. That is, the anchor pin has a generally uniform diameter across its length excluding the areas in which the recess or flat is arranged. A brake shoe includes a web having an aperture. The end portion of the anchor pin is at least partially disposed within the aperture. The aperture has a second interlocking profile complimentary to and mating with the first interlocking profile of the anchor pin to prevent relative rotation between the web and the end portion. The brake shoe and anchor pin will rotate in unison about the pivot point defined by the anchor pin to ensure the pin does not bond to the spider.
