RV Electromagnetic Brake
12.25″×2.5″, 8,000 lbs, 4-Bolt Hydraulic Trailer Brake Assembly
Key Features
- Strong overload braking capability
- Wear-resistant and aging-resistant; durable for outdoor use
- High versatility with broad modification compatibility
- Easy Maintenance: Universal Accessories
Product Overview
The 8KH heavy-duty drum brake is specifically designed for axle systems of 8,000-pound American-style trailers, RVs, and freight trailers, supporting both electromagnetic and hydraulic braking configurations. Featuring thickened brake shoes with high-performance wear-resistant friction pads, combined with a corrosion-resistant housing and a high-strength hub mounting structure, it delivers stable braking output and smooth, linear response, making it ideal for demanding heavy-duty applications such as outdoor construction sites, long-haul freight transport, and recreational RVs. It is the preferred braking assembly for heavy-duty trailer axles.

III. Maintenance Requirements
After use under muddy, rainy, or snowy conditions, clean the hub and brake sealing structures to extend their service life.
Quartly inspection: brake shoe wear, braking performance, spring elasticity, and hub bearing seal integrity
Overloading is strictly prohibited to protect the shaft, bearings, and brake assembly structure.
Apply grease according to the recommended usage cycle and maintain the bearings.
During descent, avoid prolonged continuous braking to prevent brake thermal degradation.
The structure is robust and capable of withstanding heavy loads, featuring smooth driving and braking performance.
Corrosion-resistant and wear-resistant treatment for extended service life in outdoor environments
Modular assembly for easier installation and routine inspection
Reduce driving vibrations and enhance towing safety and smoothness.
Supports customization for multiple specifications, compatible with various medium and large trailers
Reduce maintenance frequency and save long-term operating costs
