Care information
Care information
To ensure optimal performance and extend the service life of your new trailer components, please follow these care guidelines after purchase:
- Before installation, check all parts for shipping damage or missing components. Do not install damaged parts.
- Always use correct tools and torque settings. Improper installation can lead to premature wear or failure.
- For bearings, suspensions, and brake components, apply high-quality trailer grease before first use if not pre-greased.
- Some parts (like brake assemblies) require a short break-in period to achieve full performance. Follow manufacturer instructions for best results.
- Recheck fasteners, grease levels, and moving components after 100 miles of towing, then at regular intervals.
- After exposure to water, road salt, or mud, clean and dry parts thoroughly. Apply anti-rust treatment if needed.
- If storing unused parts, keep them in a dry, sealed container away from moisture and direct sunlight.

Product Overview:
This 8,000 lb electric trailer brake assembly is built for heavy duty trailers equipped with 12-1/4" x 3-3/8" drum brakes, delivering strong, consistent stopping power under demanding loads. Designed for axles rated up to 8,000 lbs, these brakes are ideal for equipment trailers, livestock trailers, flat beds, and other commercial or industrial towing applications.
Each brake comes fully assembled with brake shoes, springs, and magnet mounted on the backing plate for fast, hassle-free installation. The self-adjusting design automatically maintains proper shoe-to-drum contact during normal braking, reducing maintenance while ensuring reliable performance over time.
These brakes assemblies are available in flexible purchase options to match your service needs. You can buy a single left-hand or right-hand brake, a matched pair, two pairs, or two pairs bundled with four double-lip grease seals (2.25" ID × 3.376" OD) for a complete axle or tandem axle brake service solution.
