Dexter's 12 × 2-inch 6,000 lb electric brake uses a five-fastener backing-plate arrangement and a manual adjuster. The factory exploded view identifies the left and right assemblies, actuating levers, magnet, shoe kit and different spring arrangements used across production years.

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 6,000 lb brake family is listed separately from Dexter's 7,000 lb 12 × 2-inch assemblies, even where the drum dimensions look the same. Verify the original axle label and brake assembly number rather than using the two measurements alone. Complete assembly 023-105-00 is a left-hand brake; K23-105-00 is its cataloged kit reference.
Dexter's October 2019 bulletin explains that its 12-inch electric brakes returned to dual retractor springs after an interim single-spring design. The manufacturer warns not to mix individual anchor-post and spring components across versions. A replacement complete brake assembly can be selected under the maker's interchange instructions, but its service springs must match its construction.
K71-105-00 is the 6K magnet kit with a white lead and is linked to the matching NewRVParts listing. K71-127-00 appears as the factory shoe-and-lining number but remains unlinked because the present store listing uses a different brake diameter. Check the manufacturer service sheet before buying brake shoes.
