VEVOR 3500 lb Trailer Brake Kit with 4 Assemblies + 4 Drums for Heavy Trailers

When hauling heavy equipment, you need a braking system that can handle the load. The VEVOR 3500 lb trailer brake kit is specifically designed for tapered axle trailers and offers a high load capacity. To make your upgrade easy, the package includes four electric brake assemblies and four matching brake drums.


This complete set provides components to equip all braked wheels on your trailer. It is perfectly suitable for a wide range of vehicles, including large trailers, family caravans, and heavy RVs. It provides the essential stopping power you need to stay safe on the road, no matter how much gear you are carrying.


10 x 2-1/4 Inch Electric Brake Assemblies with Matching 10 Inch Cast Iron Drums

Size and material quality are the keys to a reliable brake. This kit features a standard brake size of 10 x 2-1/4 inches, with a matching 10-inch drum diameter. VEVOR uses cast-iron brake drums because they offer exceptional strength and effective heat dissipation. The steel brake assemblies are built for maximum durability under high pressure.


This combination ensures proper contact every time you hit the pedal. It creates a stable stopping experience that feels smooth and controlled. By using premium cast iron and steel, we ensure that these parts don't warp or fail when you are towing in difficult conditions.


Self-Adjusting Brake Mechanism for Automatic Gap Control and Consistent Braking

Our 3500 lb trailer brake kit addresses this issue with a self-adjusting brake mechanism. This system automatically maintains the correct gap between the brake shoe and the drum. You won't have to worry about manual gap settings ever again.


This smart design significantly reduces the need for frequent brake inspections. It ensures your braking performance remains consistent even on long road trips. Because the brakes adjust themselves while you drive, you always get a fast and reliable response from your trailer's wheels.


GG-Rated Semi-Metallic Brake Pads with 0.48 Friction for Strong Stopping Power

The material on your brake shoes determines how quickly you can stop in an emergency. VEVOR uses semi metallic brake shoes with a high friction coefficient of 0.48, giving them a professional GG rating. These pads are designed to be heat-resistant, so they won't fade during long downhill runs.


The composition of these shoes also helps reduce loud braking noises. They provide strong, quiet stopping power that you can rely on even during frequent braking in heavy traffic. This setup keeps your trailer under control without the annoying squeals of lower quality pads.


Pre Assembled Electric Brake Units for Fast Installation with Minimal Setup Steps

These electric brake units are factory preassembled. This means you do not have to deal with a box of loose springs and clips. No complex assembly is required on your part. Simply connect the wiring before use and follow the user manual for mounting instructions.


This efficiency makes the entire 3500 lb trailer brake kit a simple, hassle-free solution for any DIY owner. It saves you significant time and effort during installation. It lets you get your trailer back on the road much faster than a standard kit.


Steel Brake Assemblies and Cast Iron Drums with ≥30000 km Service Life

When you buy a brake kit, you want it to last for years. Our steel brake assemblies and cast iron drums are built for a minimum tested service life of 30,000 km under normal use. The steel components are shock-resistant, while the cast-iron drums can withstand typical road impacts and loads.


This kit is specifically designed to withstand rough, uneven roads. It maintains its durability even under constant load stress. This long lifespan means you can travel with confidence, knowing your brakes are built to handle the miles ahead without needing replacement anytime soon.


Integrated Dust Shield Design to Protect Brake System from Debris and Wear

Dirt, rocks, and road debris are the enemies of a healthy brake system. To fight this, our 3500 lb trailer brake kit features a built-in dust shield. This shield prevents dirt and debris from entering the brake's internal parts. It is especially important when you are driving on bumpy or unpaved roads.


By keeping the internals clean, the shield protects the brake components from unnecessary wear. It helps extend the overall lifespan of your entire braking system. It maintains your braking reliability even in harsh, dusty, or muddy conditions.


VEVOR 3500 lb Trailer Brake Kit with Axle Brand Compatibility for Secure Fitment

A universal fit is only good if it actually works with the top brands. Our kit is fully compatible with Al-Ko, Dexter, and Lippert axles. It is designed to match industry-standard mounting patterns, helping ensure a secure, proper fit when properly matched.


This wide compatibility makes it a reliable choice for the most common trailer axle systems on the market today. You won't have to worry about mismatching parts or loose fitment. It provides a secure, professional connection you can trust for all your towing needs.

What is the bolt pattern (PCD) on the brake drum? (for the tire/rim) 5 on 5.63 in / 143mm is listed, but this is not a standard pattern. The other 10x2-1/4" brakes listed have a 5 on 4.5" pattern - which is by far the most prevalent for 3500lb trailer axles.
