Ultra-Fab Electric Self-Adjusting Trailer Brake Assembly – 12" x 2" – 7,000 lb Axle – Right Hand (Passenger Side) – Boxed | 48-979255

Restore your trailer's stopping performance with the  Ultra-Fab 48-979255 Self-Adjusting Electric Trailer Brake Assembly, engineered for dependable braking, long-lasting durability, and hassle-free maintenance. Designed specifically for  7,000 lb trailer axles, this 12" x 2" right-hand (passenger side) electric brake assembly automatically maintains proper brake shoe adjustment as the brakes wear, helping deliver consistent braking performance without the need for routine manual adjustments. It is designed for trailers equipped with  electric drum brake systems and is an ideal replacement for worn or damaged OEM brake assemblies.

Built with premium automotive-grade friction material that is fully bonded to the brake shoes, the Ultra-Fab brake assembly provides increased braking torque, reduced brake fade, and longer service life. The heavy-duty E-coated backing plate helps resist rust, corrosion, road salt, and harsh weather, making it an excellent choice for travel trailers, fifth wheels, cargo trailers, utility trailers, equipment trailers, horse trailers, and other heavy-duty towing applications.

The factory-installed self-adjusting mechanism continually compensates for normal brake shoe wear during operation, ensuring optimal contact between the brake shoes and drum. This automatic adjustment improves braking consistency, extends brake life, and eliminates the inconvenience of periodic manual brake adjustments required by traditional assemblies.

Designed as a direct replacement for many popular trailer brake systems, the Ultra-Fab 48-979255 installs on standard 5-bolt brake flanges used on most 7,000 lb trailer axles. It also cross-references with several Dexter® and Lippert® brake assemblies, making replacement quick and straightforward.
