This electric brake assembly is NOT used on Dexter axles. It is found on trailers with imported axles and is hard to find. So far, we know trailers made by Quality Trailer, H and H Trailer, J and J Trailer, and Lippert Trailer have been found to use this brake assembly, and we're sure there are others.
