This electric brake assembly uses an electromagnet for actuation, requiring only an electric brake controller (sold separately). The Nev-R-Adjust system automatically adjusts during forward travel, ensuring consistent braking performance. Commonly used on utility trailers, boat trailers, snowmobile trailers, car hauler trailers, camper trailers, cattle trailers, and horse trailers. Also compatible with AL-KO, Besser Pro, Quality, Lippert, and Rockwell axles with matching specifications.
Installation Note: New Nev-R-Adjust brakes should be burnished by applying the brakes 20 to 30 times from 40 mph to 20 mph, allowing cooling between applications.
