12.25″×3.375″, 10,000 lbs, 4-Bolt Electric Trailer Brake Assembly

Key Features

Heavy-load electromagnetic braking with strong braking force
Wear-resistant, high-temperature resistant, and excellent resistance to thermal fading
Electromagnetic control structure for effortless operation
Overloaded modular design for easy maintenance

Product Overview

The 10KE Heavy-Duty Electromagnetic Drum Brake is specifically designed for 10,000-pound heavy-duty trailers, large recreational RVs, and engineering/agricultural trailers. It features an electromagnetically activated braking system with a 12.25-inch oversized brake drum, reinforced wear-resistant brake shoes, and a 4.0-inch thick-walled tube axle assembly. The entire unit undergoes heat treatment reinforcement and dual anti-corrosion processes, delivering rapid braking response and high braking torque, making it ideal for outdoor conditions such as muddy terrain, rain/snow, and long-distance heavy towing operations. This represents an upgraded electromagnetic braking assembly for American-style heavy-duty trailer axles.

Maintain (Maintenance Requirements)

After use in muddy, rainy, or snowy conditions, clean the brakes, wheel hub seals, and electromagnetic wiring to enhance durability.
Quarterly inspections: brake shoe wear, electromagnetic braking performance under power supply, spring elasticity, and hub bearing seal integrity
Overloading is strictly prohibited to protect the shaft, bearings, and electromagnetic braking mechanism.
Lubricate the bearings regularly and check the circuit’s waterproofing during the specified service cycle.
Use intermittent braking during heavy downhill loading to prevent brake thermal degradation caused by continuous high temperatures.

The structure is robust and capable of withstanding heavy loads, ensuring stable braking during towing.

Anti-rust and wear-resistant manufacturing process ensures longer service life outdoors.

Modular assembly for easier installation and routine inspection
