Genuine Dexter 10" electric brake assembly for 4,400 lb trailer axles manufactured AFTER May 2009. Available in Left Hand (K23-462-00) or Right Hand (K23-463-00). This is the revised-hole-pattern version that replaced the earlier K23-478-00/K23-479-00 brakes when Dexter updated their 4.4K backing plate design in May 2009. Pre-assembled with backing plate, brake shoes, magnet, springs, and mounting hardware — ready to bolt on.

🔧 Select Your Side

Choose Left Hand (LH / Driver Side) or Right Hand (RH / Passenger Side) from the dropdown above. Tandem-axle trailers typically need a pair of each (two LH + two RH).

⚠️ VERIFY AXLE DATE BEFORE ORDERING: This brake is ONLY for 4.4K axles manufactured after May 2009. If your axle pre-dates May 2009, you need the older Dexter K23-478-00 (LH) / K23-479-00 (RH) version instead. Check your axle manufacturer tag for the build date.
