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:

Upgrade your trailer's braking performance with this 12.25" x 3.375" hydraulic brake assembly, designed for 10,000 lb trailer axles and heavy duty towing applications. Built for reliability and ease of installation, these forward self-adjusting brakes provide strong, consistent stopping power with reduced maintenance. 

One pair includes one left-hand and one right-hand brake assembly, fully assembled on heavy duty backing plates with premium brake shoes, wheel cylinders, return springs, and adjusters pre-installed.

Available purchase options include one complete pair (LH+RH) or two complete pairs, making it easy to service a single axle or tandem axle setup. 

Perfect for use on gooseneck trailers, dump trailers, livestock haulers, flatbeds, and equipment trailers, this bolt-on hydraulic brake set delivers dependable braking and confidence when hauling heavy loads.
