Dexter 12 x 2 Inch Electric Brake Assembly, Left Hand, K23-458-00, 6000 lb CSA Nev-R-Adjust

The Dexter K23-458-00 is a 12 inch x 2 inch electric trailer brake assembly built for the left hand (LH) side of the axle. It uses Dexter's Nev-R-Adjust self-adjusting mechanism, which automatically compensates for lining wear so the brake maintains consistent stopping performance without manual adjustment. The assembly is CSA certified for use on trailer axles rated in the 5,500 to 7,000 lb capacity range, and is designed for a nominal 6,000 lb capacity position on the axle.

Because this is a side-specific component, the K23-458-00 fits the left hand position only. The right hand counterpart is a separate part number, K23-459-00, so be sure to order the correct side for your axle. Axles in this capacity range are available with 8 on 6.5 inch hub bolt patterns. This brake assembly weighs 11 pounds.
