Dexter Axle K2344700 12-1/4" x 5" Electric Forward Self-Adjusting Drum Brake Assembly Right Hand 15K

The Dexter Axle K2344700 is a complete right-hand (passenger side) electric drum brake assembly designed for heavy-duty trailer axles rated at 15,000 lbs per pair (7,500 lbs per side). Built to Dexter's exacting standards, this assembly is engineered for reliable stopping power on high-capacity trailers including gooseneck, flatbed, livestock, and equipment hauling applications.

This brake features Dexter's Forward Self-Adjusting (FSA) design, which automatically compensates for brake shoe wear on both forward and reverse stops. As lining wear creates additional clearance between the shoes and drum surface, the adjuster mechanism rotates the screw assembly to expand shoe-to-drum contact — eliminating the need for manual adjustments and reducing routine maintenance demands.

Key Features:

• Drum Size: 12-1/4" diameter x 5" wide
• Capacity: 15,000 lbs per pair (7,500 lbs per side)
• Side: Right hand (passenger side / curb side)
• Actuation: Electric — requires an electric brake controller only; no hydraulic lines or actuator needed
• Self-Adjusting: Forward Self-Adjust (FSA) mechanism adjusts on forward and reverse stops
• Backing Plate: Heavy-duty cast spider/backing plate for superior rigidity and durability
• Mounting: 7-bolt axle brake flange pattern
• Magnet Wire: Blue wire magnet
• Wheel Compatibility: Fits 15" or larger wheels
• Complete assembly — ready to install

This brake assembly installs directly onto Dexter 15K axles equipped with a 7-bolt cast brake flange. The electric design simplifies installation compared to hydraulic systems, requiring only connection to an electric brake controller. The FSA self-adjusting feature maintains consistent brake performance over the life of the lining, extending service intervals and improving safety. Also known as part number K23-447-00.
