Genuine Dexter 12" x 2" Electric Brake Assembly for 5,200–7,000 lb trailer axles. Available in Left Hand (K23-180-00) or Right Hand (K23-181-00) configurations. This is the standard manual-adjust version — an economical, reliable choice for trailer brake replacement. Pre-assembled with backing plate, shoes, magnet, springs, and hardware.

🔧 Select Your Side

Choose Left Hand (LH / Driver Side) or Right Hand (RH / Passenger Side) from the dropdown above. Tandem-axle trailers with brakes on both axles typically need a pair of each (two LH + two RH). Always replace brakes in matching pairs for even wear.

⚠️ Manual Adjust Note: These brakes require periodic adjustment every 3,000 miles or whenever braking performance decreases. Consider upgrading to Dexter Nev-R-Adjust (K23-464-00 / K23-465-00) to eliminate manual adjustment.

💡 Pro Tip: After installation, adjust brakes and burnish by applying 20–30 stops from 40 to 20 mph. Re-adjust after the first 200 miles. Always replace in matching pairs.
