Dexter Axle Electric Trailer Brake Assembly K23-181-00, 12 x 2 Inch, Right Hand, 7,000 lb, CSA

The Dexter Axle K23-181-00 is a complete 12 x 2 inch electric trailer brake assembly built for the right hand (RH) side of a 7,000 lb trailer axle. It is an electromagnetic drum brake unit designed to bolt directly onto the axle flange, giving the trailer's electric brake controller a matched, ready-to-install backing plate and magnet assembly rather than requiring separate sourcing of individual brake components. The assembly carries CSA certification, making it suitable for trailers that require CSA-approved braking hardware.

Because this is a right hand unit, it is designed for one specific side of the axle only. The left hand counterpart for the opposite side of the trailer is a separate part, Dexter K23-180-00, so trailer owners replacing brakes on both sides need to order both part numbers, not two of the same one. The kit ships as the main brake component; it is the core electric brake assembly rather than a full hardware bundle with separate mounting fasteners.
