Dexter Axle K23-459-00 Right Side 12 x 2 Inch Electric Trailer Brake Assembly, Nev-R-Adjust CSA, 5200 lb Axle, Replaces 023-459-00

The Dexter Axle K23-459-00 is a complete 12 inch x 2 inch electric drum brake assembly built for the right side (curb side) of a trailer axle rated to 5200 pounds. It uses Dexter's Nev-R-Adjust CSA design, a self-adjusting electric brake mechanism that maintains proper shoe-to-drum clearance automatically as the linings wear, reducing the need for manual adjustment over the life of the brake. The assembly is supplied complete and boxed, and includes the brake instruction sheet (059-726-00) to guide installation and setup on a compatible 12 x 2 electric brake axle.

Because this is a side-specific part, the K23-459-00 is engineered exclusively for the right side of the trailer. The left-side counterpart is a separate part number, K23-458-00, and the two are not interchangeable; installing the wrong side will not seat or actuate correctly. This right-side assembly is intended as a direct fit replacement for worn or damaged electric drum brakes on 5200 lb capacity trailer axles using the 12 x 2 Nev-R-Adjust CSA electric brake system.
