Genuine Dexter Nev-R-Adjust® 12" x 2" self-adjusting electric brake assembly for 5,200–7,000 lb trailer axles. Available in Left Hand (K23-464-00) or Right Hand (K23-465-00). Unlike standard manual-adjust brakes, Nev-R-Adjust brakes feature Dexter's innovative forward self-adjusting mechanism that automatically maintains optimal shoe-to-drum clearance during forward travel — delivering consistent braking with virtually zero maintenance.

🔧 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). Always replace brakes in matching pairs for even wear.

⚙️ Key Features
