K71-651-00 Electric/Hydraulic Trailer Brake Actuator

Upgrade your trailer brake system with the K71-651-00 electric/hydraulic actuator. Designed for hydraulic drum and disc brakes, this 12V unit offers stable pressure, smooth control, and safe, reliable towing.
Key Features

● High-Performance Brake Actuation
Delivers a stable 1600 PSI hydraulic output, ideal for most hydraulic disc brakes; compatible with inertia-type electric brake controllers for precise, efficient braking response.

● Standard 12V Power & Stable Wiring
Powered by the tow vehicle’s 12V electrical system; 4-wire design (black/blue/white/yellow) with clear color coding; operates reliably with a battery voltage of 12.5V or higher, minimizing voltage drop for consistent performance.

● Easy Installation & Maintenance
Bolt-mount design for simple setup;  install level with the filler neck facing upward; works with DOT 3 / DOT 4 / DOT 5 brake fluid; built-in sleep mode preserves battery power during long-term storage.

● Comprehensive Safety Protection
Supports emergency breakaway systems with a 12V 9Ah minimum battery; activates automatically on brake signal; ensures safe braking if the trailer detaches from the tow vehicle.

● Stable & Durable Construction
Fully protected internal electronics; no drilling, welding, or electrostatic painting on the housing to preserve integrity; proper bleeding and adjustment maintain consistent braking and extend service life.

Important Safety Warnings

●Battery Requirement: Use only maintained batteries with voltage ≥ 12.6V; do NOT use fast-charge batteries.
●Brake Fluid Rule: Use only new, sealed DOT 3 / DOT 4 brake fluid; do NOT mix fluids or use opened containers; fill fluid to 3/8 inch below the filler neck to prevent overflow. 
●Installation Prohibition: Do NOT drill, weld, or electrostatically paint the unit to avoid internal damage.
