A drum brake spider assembly (100) for an expanding shoe drum brake (10) having a removable anchor pin (18) is provided. A spider member (14) is provided with an anchor pin receiving bore (39) in which the anchor pin is removably received. The anchor pin receiving bore is provided with a first counterbore (114) at the inboard end thereof and a second counterbore (118) at the outboard end thereof. The anchor pin is provided with two annular grooves (122 and 124) in which are received first and second snap rings (128 and 130). The diameter (116) of the first counterbore is smaller than the outer diameter of the first snap ring when the snap ring is radially expanded sufficiently to remove same from the first groove in the anchor pin.
