Parts by factory drawing reference
The manufacturer numbers below describe individual components or complete brake kits. A blank product column means no exact, suitably documented current purchase link is provided. A brake kit beginning K23 is a different catalog number from an assembly beginning 023.

Matching NewRVParts product photographs
Compare these existing catalog products with the component number on your brake. The diagram is an identification reference; always confirm the axle, brake diameter, lining width and left/right side before ordering.


Choose the right brake and repair parts
The right-hand complete brake assembly is 023-181-00, while 023-180-00 is the left-hand counterpart. Dexter's 6,000 lb 12 × 2-inch brake is a distinct model family with a different magnet kit, so axle rating and the full original assembly marking matter. This page covers manual-adjust brakes, not the separate Nev-R-Adjust mechanism.
For the 12-inch 7K brake, the catalog identifies dual springs 046-009-00 for the earlier and later configurations and the interim single spring 046-005-00. Dexter's bulletin specifies matching spring and anchor-post designs when servicing individual components, rather than combining parts from the different revisions.
K71-125-00 is Dexter's magnet kit for the 7K family and is linked to an exact NewRVParts listing. K71-127-00 is listed in the exploded chart as the shoe-and-lining kit, but its existing store description needs a dimension check, so it is not linked from this page.
