Dexter K23-479-00 RH Electric Nev-R-Adjust Trailer Brake Backing Plate, 10 x 2.25 Inch, New Style Flange

The Dexter K23-479-00 is a right hand (RH) electric brake backing plate assembly built around Dexter's Nev-R-Adjust self-adjusting brake design. It is sized for 10 inch x 2.25 inch drum brakes and is rated for axles in the 2300 to 4000 pound capacity range. The backing plate carries a new style flange, so it is intended for axles and hubs machined to accept the newer flange pattern rather than older flange configurations.

Because this is a right hand (RH) specific part, it is built and drilled to mount on the right side of the trailer axle only. It is not interchangeable with a left hand (LH) unit; the opposite side of the axle requires a separate Dexter part number. The Nev-R-Adjust electric brake system is designed to automatically compensate for shoe wear, reducing the need for manual brake adjustment over the life of the linings. This kit is sold as a replacement/service part for trailer axle brake systems and is intended for installation by someone familiar with trailer axle and brake servicing.
