This is a complete 12-1/4" diameter electric brake assembly made by Dexter®. A complete, or otherwise known as "loaded", brake comes pre-assembled and ready to be mounted onto your flange with existing bolts and nuts. If existing harware is no longer useable, new ones are available here for purchase. This brake uses a forward self adjusting feature which adjusts the brakes on each forward stop. As the shoes wear on the drums, the adjuster arm rotates the screw assembly at the bottom of the brake, expanding the shoes to fill in the gap.
