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

12.25 x 3.375 Inch Trailer Electric Brake Kit for 8000 lbs Axles

RVs and trailers with axle capacities up to 8,000 pounds can use the 12.25-by-3.375-inch brake units included with the VEVOR trailer electric brake kit. This size ensures that medium- to heavy-duty trailers can stop reliably, giving drivers precise control no matter what kind of load they are carrying.


These brakes are great for pulling camping trailers, big loads, or recreational vehicles because they are extremely safe. Because they are big and can hold a lot of weight, they are strong and stable enough to handle rough roads. To make towing safer, they also have smooth, steady stopping power.


Trailer Electric Brake Kit: 1 Pair Self-Adjusting Brake Assemblies for Easy Maintenance

You won't have to keep adjusting the brakes by hand because this kit comes with two electric drum brake systems that can do it for you. Even when pulling a heavy load or towing a lot, the smart, self-adjusting mechanism keeps the brake shoe-to-drum gap at the right level. This helps the brakes on your trailer work well and respond quickly.


This feature prevents brake wear and ensures that people who drive a lot or take long trips can always stop. You don't have to do much to ensure the stopping system on your trailer is always working at its best; these parts take care of themselves.


Fits Most Trailers and RVs with 4 Holes on a 5 Inch Bolt Circle

Your RV or trailer needs 4 holes on a 5-inch bolt circle to use the VEVOR trailer electric brake kit. It works with a wide range of trailers, even recreational vehicles, thanks to the way the bolts are set up.


Don't make any changes or spend a lot of money on fittings to install these brakes. They just fit with normal bolt patterns. Because these assemblies work so well together, users can safely modify or improve their current brake system. They work with many trucks and axles that can hold up to 8,000 pounds.


Automatic Brake Adjustment for Consistent Gap and Responsiveness

A brake adjustment in the trailer's electric brake kit maintains the distance between the brake shoes and the drum. This keeps the brakes smooth and fast, even when stopping quickly or often. The system stays in the right place longer because it is automatic, and the stop parts don't wear out unevenly.


This function improves brake performance for people who pull trailers for work, travel, or fun. It's safer and more reliable to stop, especially when going down steep hills, stopping quickly, or pulling big loads for a long time.


Semi-Metallic Brake Shoes with 0.48 Friction Coefficient for Stable Braking

Designed to work reliably and consistently under heavy loads, the kit comes with semi-metallic brake shoes with a nominal friction coefficient of around 0.48 (GG level). These brake pads can handle high temperatures and last a long time. They keep the brakes working well even when going downhill or stopping repeatedly.


Semi-metallic pads are strong, durable, and quiet. They help improve braking control and confidence. They are excellent for both personal and business trailer use because the brakes are responsive, noise levels are low, and maintenance costs are low.


Shock-Resistant Steel Construction with Protective Shield for Durability

Due to their shock-resistant steel construction, these trailer electric brake assemblies can withstand typical towing vibrations, impacts, and rough road conditions. The protective shield keeps dust, dirt, and water out of the brake assembly, ensuring long-lasting durability and consistent stopping power.


The robust design of the brakes means they will last a long time, even when used on rough terrain or with heavily loaded trailers. VEVOR offers a reliable braking system that enhances safety and reduces the risk of premature wear or component failure by combining strength and protection.


Easy Installation with Pre-Assembled Core Parts and Simple Manual Steps

The preassembled core parts make it easy to install the VEVOR trailer electric brake kit. To finish the installation, users only need to add brake oil and follow the step-by-step instructions provided with the product. The well-thought-out design reduces installation time and mistakes, so both do-it-yourselfers and skilled mechanics can use it.


Users can quickly and easily improve their trailer's braking system with clear instructions, pre-assembled core parts, and ready-to-use components. This ensures their trailer or RV is fully prepared for the road, meets safety standards, and is ready for long-distance towing or heavy-load use without any extra delays, confusion, or installation issues.


≥30,000 km Lifespan for Long-Term, Heavy-Duty Performance

The steel construction, semi-metallic pads, and safety features all add up to a service life of about 30,000 km, meaning they will work well and reliably for years. With these electric trailer brakes, you can tow frequently, haul heavy loads, and go on long trips with consistent braking performance.


Durable steel construction, semi-metallic brake pads, and smart design all work together to deliver consistent, reliable stopping power over long distances. This kit is a professional-grade, cost-effective option for trailer owners who need high-quality brake assemblies that withstand heavy-duty use.
