Dexter Axle Left Hand Electric Brake Assembly 10 x 2-1/4 Inch, Nev-R-Adjust Self-Adjusting, K23-478-00, 2300-4000 lb Axle Capacity

The Dexter Axle K23-478-00 is a complete left-hand (LH) 10 inch x 2-1/4 inch electric brake assembly built for trailer axles rated from 2300 to 4000 pounds capacity. 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.

This 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.
