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. The forward self-adjusting design automatically maintains proper shoe-to-drum clearance as components wear, helping ensure smooth braking performance over time.

These brakes mount to a 7-bolt brake flange and are ideal for axle rebuilds or brake replacements on 10,000 lb axles. Constructed from durable steel with a corrosion-resistant finish, they are built to withstand demanding hauling conditions.

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.
