It uses Dexter's Nev-R-Adjust self-adjusting mechanism, which automatically takes up shoe wear during normal reverse-direction braking so the brakes maintain proper clearance without periodic manual adjustment. The assembly mounts to a 4-bolt backing plate and includes the complete left-hand brake assembly as a single unit, ready to install on a compatible Dexter trailer axle.\u003c\/p\u003e\u003cp\u003eThis is the left-hand side assembly only. Dexter also offers the K23-479-00 (RH Electric Nev-R-Adjust) as the matching right-hand counterpart and the K23-463-00 (RH Electric) as a separate right-hand part -- be sure to order the correct side for your axle position, as these are distinct part numbers and installing the wrong side will not fit correctly.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Dexter Axle\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e K23-478-00\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Electric Brake Assembly\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSide:\u003c\/strong\u003e Left Hand (LH)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrake Size:\u003c\/strong\u003e 10 inches x 2-1\/4 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAxle Capacity:\u003c\/strong\u003e 2300 to 4000 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustment Type:\u003c\/strong\u003e Nev-R-Adjust self-adjusting\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBacking Plate:\u003c\/strong\u003e 4-bolt\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIncluded Components:\u003c\/strong\u003e Complete left-hand brake assembly\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 12 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 876983004768\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWarranty:\u003c\/strong\u003e Limited 1 year\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOEM Equivalent Part Number:\u003c\/strong\u003e 023-478-00\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Trailer drum brakes\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eFits Dexter trailer axles rated 2300 to 4000 pounds capacity equipped with electric brakes on the left-hand side.\u003c\/p\u003e\u003ch3\u003eReplaces (OEM)\u003c\/h3\u003e\u003cp\u003e023-478-00\u003c\/p\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eIs the K23-478-00 a left-side or right-side brake assembly?\u003c\/strong\u003e The K23-478-00 is the left-hand (LH) electric brake assembly.
