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 Description:

Upgrade your trailer's braking performance with these 12.25" × 3.375" self-adjusting hydraulic brake assemblies, engineered for 9,000 - 10,000 lb general duty trailer axles. Each set includes a matched left hand and right hand brake, fully assembled with brake shoes, wheel cylinders, return springs, and adjusters for a true bolt-on installation with no additional setup required.

Designed to mount on a standard 7-bolt brake flange, these brakes are OEM compatible replacement for Dexter K23-410-00 (right hand) and K23-411-00 (left hand), ensuring precise fitment and dependable stopping power. The forward self-adjusting design automatically maintains proper shoe clearance as the brakes wear, reducing maintenance while delivering consistent, confident braking.

Built from heavy duty steel with a corrosion resistant finish, these brake assemblies are made to withstand demanding hauling conditions. Ideal for gooseneck trailers, flatbeds, livestock haulers, dump trailers, and equipment trailers, they're a reliable solution for full axle rebuilds or brake upgrades, getting your trailer safely back on the road with minimal downtime.
