A spacer (10) is used to prevent a vibratory noise created by two inelastic parts of a drum brake assembly (12) from contacting each other; the two inelastic parts being the backing plate (18) and the brake shoe (28). The spacer (10) is fabricated from an organic polymeric material based on acetal. The spacer (10) comprises a head (30) and an anchor (34). The head (30) is cylindrical in shape with a rounded distal end (32). The rounded distal end (32) is the end that contacts the backing plate (18) and absorbs any vibratory energy which may produce a noise if the vibratory energy contacted an inelastic object, i.e., the brake shoe (28). The anchor (34) is extended through a hole in the tab (26) and is secured thereto because the fluted edges (36) of the anchor (34) are forced through the hole (not shown) in the tab (26).
