Beware of the brake assemblies with gold colored metal at the brake shoes. Most of those are China made.
In May of 2000 Dexter redesigned the brake assembly with a cast backing plate (The ears that hold the brake shoe to the backing plate) If you have the older style you can replace it with this newer style.
