7" Trailer Electric Brake

Trailer electric brake systems are essential components for modern towing. They bridge the power gap between tow vehicles and heavy trailers, delivering precise and responsive stopping control. Whether you haul recreational vehicles, cargo trailers, livestock carriers or heavy equipment, electric trailer brakes turn risky, unbalanced towing into a safe and reliable experience. Combining electrical precision with mechanical durability, our brakes set high standards for towing safety.

• Brake specification: 7 inches (177.8mm) diameter × 1.25 inches (31.75mm) width
• Working voltage: DC 12V (compatible with standard vehicle power supply systems)
• Axle load rating: 2000–2200 lbs (900–1000kg) per axle
• Mounting interface: 4-bolt flange, mounting bolt size: 7/16 inch
• Adapted wheel size: 10/12/13-inch trailer hubs
• Brake structure: Electric drum type, separate left and right design
• Adjustment mode: Manual adjustment (equipped with dustproof adjustment plug)
• Certification standard: Compliant with QAI, CSA, SAE-N and other industry specifications
• Net weight: Single unit: approx. 4.5 lbs; Complete set (left + right): approx. 9 lbs

This product adopts a multi-material composite design to achieve optimal strength, heat dissipation and corrosion resistance.

• Backing plate: High-strength steel plate with electrophoretic coating (E-coat), rust and corrosion resistant, ideal for humid and salt-fog environments.
• Brake drum: High-performance cast iron with outstanding heat dissipation and wear resistance, ensuring stable braking during continuous operation.
• Brake shoe: Stamped steel base bonded with automotive-grade friction material. Rivet-free structure features large contact area, low noise and long service life.
• Electromagnet: Assembly with high-conductivity copper coil and iron core, featuring strong suction, fast response and stable current conduction.
• Adjustment mechanism: Carbon steel star wheel with dustproof plug, effectively blocking sand and dust to extend the service life of internal parts.
• Fasteners: Grade 8 high-strength bolts with anti-loose design, maintaining stable connection under vibration.
   

• Precise braking response: Powered by 12V electromagnetic force, the brake activates instantly when the tow vehicle brakes. Zero delay effectively prevents trailer sway and jackknifing.
• High compatibility: Standard 4-bolt mounting design fits most light axles rated 2000–2200 lbs. Compatible with mainstream brands including Dexter, Lippert and AL-KO.
• Excellent durability & corrosion resistance: E-coated backing plate, wear-resistant friction lining and waterproof circuit design adapt to harsh conditions such as ordinary roads and coastal areas.
• Easy maintenance: Built-in dustproof adjustment plug allows quick manual adjustment without disassembly. No hydraulic oil required, eliminating leakage risks and extra maintenance work.
• Enhanced safety: Can be paired with trailer breakaway switch and backup battery. It applies brakes automatically once disconnection occurs to avoid runaway accidents.
• Smooth braking performance: Tapered edge design on friction plates ensures even force distribution. No wheel lock or jitter, protecting tires and improving driving comfort.
