VEVOR Electric Trailer Brake Kit With 12.25 x 3.375 Inch Brakes for 10000 lb Axle

With the VEVOR Electric Trailer Brake Kit, you can stop RVs and trailers that weigh up to 10,000 pounds. The brake assemblies in this kit are 12.25 inches by 3.375 inches, the perfect size and power for safely and effectively stopping big loads. You can use these brakes on both domestic and commercial trailers.


The high standards of this kit mean that it works with most trailer axles used on trucks and RVs. It's easy to connect to existing braking systems because the brake assemblies measure exactly 12.25 inches by 3.375 inches. This makes the update a smooth and safe process. You can count on VEVOR to make brake parts that last and work well.


4 Self-Adjusting Electric Brake Assemblies for Reliable Braking Performance

This kit includes four self-adjusting electric brake assemblies. These will make stopping your trailer or RV much easier. Each part instantly adjusts to maintain the correct brake gap, ensuring the brakes work well and easily, even when stopping quickly or hard. You don't have to make any changes by hand with this tool.


The four assemblies completely cover a two-axle trailer, evenly distributing stopping force and making it easier to handle the entire trailer. The kit ensures all four wheels have good brakes, keeping the caravan safe on long trips and steep hills. The brakes on your trailer work better and more effectively after you add these parts.


Electric Trailer Brake Kit with Automatic Brake Adjustment for Consistent Gap and Long-Term Responsiveness

Don't worry about regular upkeep or manually checking the brake adjustment. Automatic brake adjustment in the VEVOR Electric Trailer Brake Kit keeps the right gap between the brake shoes and the drum. This keeps your brakes working well and prevents important parts from wearing out over time.


Automatic adjustment makes long-distance travel safer and easier for frequent travelers. The system continuously maintains the brake adjustment, so they work the same way even when the load or situation changes. This smart function keeps your brake assemblies safe and gives you peace of mind on every trip.


Pre-Assembled Brakes With Core Parts Installed for Easy Installation

With VEVOR's pre-assembled brake kit, installation is quick and easy. Each brake already has its core parts fixed, so all you have to do is connect the wiring and follow the step-by-step instructions that come with it. This reduces construction mistakes and saves time.


Because the brakes are plug-and-play, even people who don't know much about mechanics can confidently install them. The kit is easy to install and works with most caravan setups. This function lets you quickly and safely change your brakes without hiring a professional.


Semi-Metallic Brake Pads With 0.48 Friction Coefficient for Heavy Loads

This kit's brake pads are semi-metallic and have a friction value of 0.48, which means they can stop very well even when the vehicle is loaded with heavy cargo. These pads give you constant stopping power, so you can keep control on steep descents or sudden stops.


Semi-metallic pads are very strong and wear-resistant, so they will last a long time. The design that resists heat buildup keeps your brakes working reliably and consistently, even in tough conditions.


Heat-Resistant Trailer Brakes for Noise Reduction and Stable Performance

It is important that VEVOR's trailer brakes withstand heat. The steel assemblies and semi-metallic pads keep noise and vibration to a minimum, making stopping smoother and towing more comfortable. The system stays stable and quiet even when it has to brake for extended periods.


This design is heat-resistant, helping prevent brake components from overheating and wearing out too quickly. The VEVOR Electric Trailer Brake Kit ensures safe, efficient heavy-duty towing by maintaining performance even in high temperatures. This kit keeps your trailer and its goods safe.


Steel Brake Assemblies With Protective Shield for ≥30000 km Lifespan

The kit comes with high-strength steel brake parts designed to last at least 30,000 km. Each assembly can handle rough roads, heavy loads, and heavy use without breaking. The long-lasting design reduces repair and replacement costs.


A shield keeps dirt, debris, and water out of the braking system, protecting its internal parts and extending their lifespan. Your trailer's braking system will remain stable and perform well with these long-lasting assemblies, even in tough conditions.


7-Hole, 5.5 Inch Bolt Circle Backing Plates for Most Trailer and RV Installations

Most trailers and RVs can use VEVOR's backing plates because they have a 7-hole, 5.5-inch bolt circle. This ensures a perfect fit without requiring any changes, making the upgrade process easier and increasing installation accuracy.


The precise design makes the fitting more stable and evenly distributes the stopping force across the axle. These backing plates ensure a solid attachment and that the plates and brakes work together effectively. They also help improve safety and brake efficiency for a wide range of trailer uses.

The description says the backing plate has a 7 bolt pattern, but the majority of the photos show the standard 4 bolt pattern for 8000 lb. axles. Which is it? Thank you
The 10000lbs model in the Applicable Pound Rating option of this product has 7 holes.
