Dexter 12 Inch x 2 Inch 6000 lb Left Hand Electric Drum Brake Assembly - 023-105-09

The Dexter 023-105-09 is a complete 12 inch x 2 inch electric drum brake assembly rated for 6,000 lb (6K) axle capacity, built for the left hand (LH) side of a trailer axle. This is a full brake assembly, not a repair kit, so it is intended for direct installation as a complete unit rather than a rebuild of an existing worn brake. Electric drum brakes of this type use a magnet-actuated shoe system that engages when the trailer's electric brake controller sends current to the magnet, drawing the shoes into contact with the drum for stopping power that is proportional to the controller's output. The 12 inch x 2 inch designation refers to the drum diameter and shoe width, which must match the trailer's hub and drum dimensions for correct fit. Because this is designated a left hand assembly, it is built for one specific side of the trailer axle; a right hand (RH) counterpart is sold as a separate, differently numbered assembly, so confirming the LH designation before ordering ensures the correct part arrives for the intended wheel position. The assembly weighs 14 pounds. Trailer owners and fleet maintenance operators use assemblies like this to replace a damaged, corroded, or failed brake unit on 6,000 lb rated axles where a full assembly swap is preferred over piecemeal part replacement.

Frequently Asked Questions

Is the Dexter 023-105-09 a left or right side brake? The Dexter 023-105-09 is a left hand (LH) electric drum brake assembly, built for the left side of the trailer axle only. A right hand version is a separate part with a different part number, so confirm the LH designation before ordering to get the correct side.

What size trailer drum does this brake fit? This assembly is sized for a 12 inch x 2 inch drum, meaning a 12 inch drum diameter and a 2 inch wide brake shoe, which is the Dexter 023-105-09 configuration.

What axle capacity is this brake rated for? The 023-105-09 is rated for 6,000 lb (6K) axle capacity, matching Dexter's 12 inch x 2 inch electric brake line for that load rating.

Does this come as a complete assembly or just replacement shoes? This is a complete electric drum brake assembly, not a shoe-only repair kit, so the full unit is included for direct installation on the left side of the axle.

How much does the Dexter 023-105-09 weigh? The assembly weighs 14 pounds.

How does an electric drum brake like this one work? An electric drum brake uses a magnet mounted inside the assembly that is energized by the trailer's brake controller; when current flows to the magnet, it pulls the actuating arm to draw the shoes into the drum, and stopping force increases with the current the controller sends, which describes how the 023-105-09 assembly operates.

Can I use this brake on a right hand hub position? No. The 023-105-09 is built specifically as a left hand assembly and should not be installed on a right hand hub position; a separate right hand Dexter part number is needed for that side.

What is the UPC for this Dexter brake assembly? The UPC for the Dexter 023-105-09 left hand electric drum brake assembly is 840327614067.

Is this brake assembly made by Dexter? Yes, this is a genuine Dexter brake assembly, part number 023-105-09.

What trailer applications is a 12 inch x 2 inch 6K electric brake used on? A 12 inch x 2 inch 6,000 lb electric drum brake assembly such as the 023-105-09 is used on trailer axles rated for that 6K capacity where the hub and drum are sized to accept a 12 inch x 2 inch brake.
