Ideal for trailers, caravans, and RVs. Whether for towing or transporting cargo, this electric trailer brake kit provides reliable security and peace of mind.

Self-Adjusting 12x2 Inch Electric Trailer Brake Assembly Eliminates Manual Brake Gap Maintenance

This electric trailer brake assembly features automatic brake adjustment technology that maintains the correct brake gap throughout its service life. So you do not have to check the brakes or make hand adjustments. The 12x2-inch brake configuration with 12-inch drums stops 6,000-pound trailers efficiently, and the self-adjusting system accounts for pad wear that naturally occurs during use.


When you use the brakes, the advanced auto-adjust feature keeps the right amount of space as parts wear down. This electric trailer brake part keeps your system responsive over time, making it perfect for frequent stops and long trips with minimal maintenance.


Heavy-Duty 6000 Pound Capacity with 0.48 Friction Coefficient GG-Level Pads

The strong design can handle trailer loads of up to 6,000 pounds, and the semi-metallic brake pads have a friction coefficient of 0.48 at the GG level for strong, reliable stopping power. These heat-resistant pads maintain consistent friction characteristics during heavy-load operation, downhill braking, and frequent stopping scenarios. They also make less noise when they are in use than regular materials.


The DC12V electromagnet has a magnetic force of at least 600N, which is sufficient to reliably activate the brakes across a current range of 2.8A to 4.2A. The GG-level rating means that the brakes will work better in tough conditions. This electric trailer brake assembly is ideal for hauling heavy loads and navigating rough terrain.


Complete Pre-Assembled Kit with Gray Cast Iron Drums and Steel Assemblies

The complete kit includes two brake systems and two brake drums, made of gray cast iron and SPHC/Q235 steel to ensure they last as long as possible. Each assembly comes preassembled, with the core parts in place. All that needs to be done is adding grease and completing the final fitting. The gray cast iron drums are better at transferring heat and keeping their shape than regular materials.


The 91.7-pound total weight shows how well-made it is, and the fact that it comes pre-assembled makes it easier to put together. Standard trailer setups will fit because the brake shoe is 13.82 inches long and 2.81 inches wide, and the drum is 12.9 inches wide and 6.69 inches deep.


Universal 5-Hole Mounting Electric Trailer Brake Assembly with AL-KO, Dexter, and Lippert Compatibility

The standard 5-hole flange mounting with a 3.9-inch PCD and a 5-Φ10 bolt pattern works with axles from AL-KO, Dexter, Lippert, and other well-known brands. Standard trailer hub setups can use the 6-bolt drum pattern with a 5.5-inch PCD and 1/2-20 UNF threading without any changes.


Designed to work with current 12V trailer electrical systems, it minimizes fitment concerns. This electric trailer brake assembly fits easily onto standard wiring harnesses, making it easy to install on most leisure and business trailers.


Extended 30,000+ Kilometer Service Life with Shock-Resistant Construction

Steel brake systems and gray cast iron drums make the brakes very durable. Under normal conditions, they can last for more than 30,000 kilometers. The design is shock-resistant, so the structure remains strong even after repeated heating and cooling. The built-in dust shield prevents road debris and moisture from entering the internal parts.


A longer service life lowers long-term operating costs and ensures reliable performance across a wide range of operating conditions. The strong materials can handle rough roads and exposure to the elements without breaking down too soon, so the brakes will always work properly for as long as the part is in use.


Precision Electromagnet with 12-Inch Configuration and 600N+ Magnetic Force

The 12-inch electromagnet specification ensures an even distribution of magnetic force across the brake assembly, resulting in consistent engagement. The ≥600N magnetic force helps the brakes work reliably across a wide range of temperatures, and the DC12V function is compatible with most trailer electrical systems.


The 2.8A to 4.2A current range works with a variety of brake controllers and maintains stable performance across a wide range of operating conditions. This electric trailer brake system has a magnetic engagement that is professional-grade and reliable enough for both business and leisure use.


Professional 2x0.2 Inch Brake Pad Design with Heat and Impact Resistance

The 2x0.2-inch semi-metallic brake pads are very resistant to wear thanks to an improved material formulation. The 0.48 friction coefficient is designed to provide consistent stopping power, and the heat-resistant qualities help prevent the brakes from wearing out over the long term. In shock-loading situations, the impact-resistant design maintains the pad's integrity.


The advanced pad makeup reduces noise while still allowing smooth operation. The carefully thought-out dimensions ensure the contact area is just right for maximum stopping power while also maintaining the part's durability in tough working conditions.


Complete Installation Package for Trailers, Caravans, and RV Applications

The kit includes the key components you need to install a brake system on a trailer, caravan, or other recreational vehicle rated for up to 6,000 pounds. The pre-assembled design and installation instructions make the upgrade process easier while ensuring all parts work properly. For correct installation, all you have to do is add grease and follow the steps one by one.


The wide range of applications makes it possible to haul cargo, move tools, and tow recreational vehicles. This electric trailer brake assembly provides greater safety and peace of mind for both occasional recreational use and demanding business applications that require reliable stopping power.
