Abstract
The present invention is a drum brake shoe assembly having an improved support structure which limits the lateral travel of the leading brake shoe, to thereby reduce or eliminate audible impacts between the brake shoe and the backing plate of the drum brake assembly. In accordance with the invention, two or more spaced apart hold down devices are provided on the leading brake shoe while a single hold down device is used on the trailing brake shoe. Each of the hold down device includes a hold down pin connected at a first end to the backing plate of the drum brake assembly. The second end of each hold down pin extends through an opening in the web of the brake shoe. Springs such as coil springs or the like are disposed between the second ends of the hold down pins and the brake shoe web for urging the brake shoe against the backing plate.
