Self-adjusting Electric Trailer Brake Kit: For 3500 lbs Trailers
This trailer brake kit includes 2 brake assemblies and 2 brake drums, fit for 3500 lbs trailers. The auto-adjust feature compensates for wear, making it an ideal upgrade for enhanced braking performance.
The electric trailer brake assembly is compatible with top axle brands like Al-Ko, Dexter, and Lippert. Pre-assembled core components make installation easy. Simply add oil, and you’re ready to go!
The self-adjusting brake mechanism ensures a smooth ride, minimizing the need for frequent brake checks. Enjoy consistent braking performance and enhanced security on steep descents.
Our self-adjusting electric brakes kit is crafted with durable GG-rated brake pads, steel brake assemblies, and cast iron drums. These components resist wear, heat, and impact, making them ideal for long trips.
Ideal for trailers, caravans, and RVs. Whether for towing or transporting cargo, this electric trailer brake kit provides reliable security and peace of mind.

10 x 2-1/4 Inch Brake Size for Reliable Braking on 3500 lbs Trailer Axles

The precise 10 x 2-1/4-inch brake size that comes with this 3500 lb axle brake kit fits most standard trailer axles rated for up to 3500 lbs. When you apply the brakes, the brake shoes press evenly and seat properly inside the drum thanks to this size. Your trailer can stop smoothly and steadily, without jerking or a weak response, as long as the contact area remains balanced.


Additionally, using the correct brake size reduces strain on the brake components. Rather than applying pressure to a single spot, it distributes braking force across the entire drum surface. As a result, components wear more slowly and retain their quality longer.


Self Adjusting Electric Brake System for Consistent Brake Gap and Long Term Performance

The intelligent self adjusting electric braking system in this axle brake kit maintains the proper distance between the brake shoes and the drum. Because the system adjusts itself when the brake pads deteriorate, you do not need to stop frequently to perform manual adjustments. This feature aids in maintaining a steady braking force even after many miles of driving.


During intensive use and lengthy trips, this automatic adjustment is particularly useful. The mechanism helps maintain a stable braking force while you drive downhill or stop frequently in traffic. This feature lowers the possibility of uneven wear and helps prevent weak braking. When towing valuable cargo or traveling with family, the axle brake kit enhances safety and gives drivers peace of mind.


Pre Assembled Brake Assembly Design for Fast Installation and Reduced Setup Time

Pre assembled means that most of the parts are in place when you open the package. Fitting small parts together does not have to take hours. All you have to do is follow the easy instructions in the manual, mount the backing plates, connect the components, and add lubricant if necessary.


Both novice and expert technicians will find this simple installation to be effective. You can swiftly complete the task and resume driving by modernizing your system or replacing your outdated brakes. By simplifying the setup process, the 3500 lb axle brake kit lets you focus more on driving and less on complicated instructions and tools.


Semi Metallic Brake Pads with 0.48 GG Friction Rating for Stable Heavy Load Control

The brake pads used in this system are semi metallic and have a friction rating of 0.48 GG. When you apply braking force, the shoes grip the drum firmly due to the high level of friction. Even when you are carrying heavy cargo, the pads help your trailer stop steadily. When you need to stop frequently on crowded routes or when traveling downhill, this feature is helpful.


During use, the pad material also helps regulate heat. Brakes function better and last longer when they are cooler. When braking, these pads provide a smooth feel and lessen loud noise. The axle brake kit is designed for freight carriers, work trailers, and RVs, providing powerful, reliable stopping capability.


Steel Brake Backing Plates for Structural Strength and Shock Resistance on Rough Roads

This kit includes steel brake backing plates that secure all major braking components. To keep the brake shoes and internal components aligned during use, these plates support them. The brakes respond better to each pedal press and operate more smoothly when the elements remain in their proper positions.


Additionally, these robust plates help absorb shocks from uneven roads. The plates help reduce system vibration when driving on gravel, bumpy roads, or uneven construction sites. This design helps reduce the chance of early damage while protecting the braking components. Even under challenging driving circumstances, the 3500 lb axle brake kit remains robust and stable.


Cast Iron 10 Inch Brake Drums for Heat Dissipation and Noise Reduced Operation

The 10 in. cast iron brake drums in this kit help dissipate heat during braking. Brakes can become very hot when you stop frequently or drive downhill. By dispersing heat across the surface, these drums help prevent overheating and brake power loss. During lengthy journeys and heavy hauling, this feature ensures consistent performance.


Additionally, cast iron helps reduce vibration within the braking system. This feature implies that while driving, you will hear less noise and experience fewer vibrations. Every stop feels more comfortable and in control because of the seamless operation. The 3500 lb axle brake system enhances both driving comfort and safety.


 Dust Shield Protection System for Debris Prevention in the 3500 lb Axle Brake Kit

The dust shield in this brake kit protects the internal components from water, dirt, and small road debris. The brake shoes and drum may move freely and perform better when dust and moisture are kept out. This defense helps prevent rust and early damage caused by harsh driving conditions.


Additionally, this barrier can reduce the need for frequent maintenance and cleaning. The components remain in good condition for a longer period of time when fewer particles enter the system. The axle brake kit is a wise option for drivers who travel on country roads, construction sites, and in damp conditions, thanks to its design.


 ≥30000 km Service Life Construction for Long Lasting 3500 lb Axle Brake Kit Performance

Designed to last at least 30,000 kilometers, this brake system features cast iron drums and sturdy steel components. These materials are resistant to deterioration from large loads and frequent braking. This design contributes to the system's long-term dependability.


Frequent part replacements are less necessary due to this extended service life. It reduces maintenance costs and time. The 3500 lb axle brake kit offers consistent braking and long-lasting performance on every journey, whether you use your trailer for work, travel, or everyday carrying.
