- 【Heavy-Duty 9K–10K Brake & Seal Kit】Includes 2 left-hand and 2 right-hand electric brake assemblies (12.25" x 3.375") plus 4 unitized oil seals—engineered for Dexter 9K/10K general-duty trailer axles.
- 【Self-Adjusting Brake Mechanism】Each brake assembly is equipped with a built-in self-adjuster that automatically maintains the correct shoe-to-drum clearance. This feature delivers consistent braking force over time without the need for manual adjustments, reducing maintenance and improving safety.
- 【Fully Pre-Assembled for Easy Installation】Brakes come pre-installed with key components—including friction shoes, return springs, electromagnets, and wiring—mounted on a durable 7-hole backing plate. Just bolt on and wire up for a fast and efficient upgrade.
- 【Premium One-Piece Oil Seals】Includes (4) unitized seals (2.875"x3.875") made from bonded rubber and metal for a tight, leak-resistant fit. Designed to prevent grease escape and block dirt, water, and road debris, these seals extend hub life and improve reliability.
- 【OEM Replacement for Dexter Axles】Brake assemblies replace Dexter part numbers K23-450-00 (LH) and K23-451-00 (RH); seals replace Dexter 010-051-00, 10-2875-06, and 10-51. Built to fit 9K/10K grease-lubricated axles commonly used on livestock trailers, goosenecks, flatbeds, and utility haulers.
