ABSTRACT:
A brake shoe assembly is provided in which the brake shoe table has at least one longitudinal channel running along the upper surface thereof. A generally smooth arcuate brake shoe lining is fastened to the table, so that a longitudinal chamber is formed comprising the channel and the portion of the bottom surface of the lining which covers the channel. The chamber is constructed so as to affect the natural excitation frequency of the brake shoe to be outside the range of the excitation frequency of the brake drum, to thereby reduce or eliminate resonance of the two frequencies upon actuation of the brake.
