Hydrastar Marine-Grade EOH Actuator
The Hydrastar Marine-Grade Electric Over Hydraulic Trailer-Mounted Brake Actuator is designed for reliability in marine environments and other demanding settings. With a 1600 PSI output, it drives hydraulic disc brakes with precise control, reducing wheel lockups and improving stability on wet or uneven surfaces. Marine-grade seals and corrosion-resistant components help extend service life in harsh weather, while the unit is compatible with standard 12V electrical systems for straightforward installation.
Key considerations
Compatibility with disc brakes, environmental durability, and ease of installation are central. Marine-grade hardware and sealed housings can be critical where exposure to saltwater or spray is common. This actuator provides robust stopping power for mid- to large-duty trailers and boats.
Dexter K71-651-00 EOH Actuator
Dexter’s K71-651-00 combines electric controls with a hydraulic pump to deliver up to 1600 PSI for disc brakes. It’s designed for reliable operation in a range of trailer applications, including camping trailers and utility trailers. The dual-function actuator simplifies wiring by offering integrated electric control for hydraulic braking performance, and it is backed by Dexter’s reputation for trailer components.
Key considerations
Check the output torque and duty cycle for your trailer weight and axle configuration. The K71-651-00 is suitable where precise control of hydraulic braking is needed, but ensure your brake drums or discs are compatible with the 1600 PSI rating to prevent over-pressurization.
Deutsche Hydrapro Alpha G1600 Actuator
The Deutsche Hydrapro Alpha G1600 is engineered for high performance with a 1600 PSI output and a weatherproof, anodized aluminum case. It uses a high-powered DC motor and a durable pump with minimal moving parts for reliability. Features include an independently sealed fluid tank for reserve fluid and protection against external elements, making it suitable for off-road trailers, RVs, and boats that face varied weather conditions.
Key considerations
Consider environmental exposure and maintenance intervals. An isolated reservoir reduces the risk of fluid loss, while the case protection helps extend life in salty air or dusty environments. Verify wiring compatibility and the control system with your existing trailer brake controller.
Hydrastar EOH Actuator (1600 PSI)
The Hydrastar Electric Over Hydraulic brake actuator from The Trailer Parts Outlet delivers 1600 PSI to hydraulic disc brakes. Its design emphasizes compatibility with a wide range of trailer types, including boats, RVs, and light commercial equipment. The unit uses a 12V DC power supply and a four-wire harness for a straightforward installation, with a sealed housing and fluid-compatible components to ensure consistent braking performance in diverse conditions.
Key considerations
Evaluate the size and mounting footprint to fit your trailer frame. Check if your current brake calipers and rotors match the 1600 PSI output to avoid braking imbalance or excessive wear on components.
Dexter BrakeRite EOH Actuator
Dexter’s BrakeRite Electric Over Hydraulic Actuator is designed for hydraulic disc brakes with a 1500 PSI output. It’s marketed for quick response times and reliable performance, emphasizing compatibility with typical trailer brake controllers. The 1500 PSI rating helps support strong braking for trailers with heavier loads or longer stopping distances, while maintaining smooth engagement and predictable deceleration.
Key considerations
Assess the brake system’s overall balance, ensuring the 1500 PSI rating aligns with your drum or disc brake assemblies. Confirm the actuator’s compatibility with your existing brake controller and wiring harness, and verify serviceability if fluid changes or pump maintenance are needed.
Buying Guide: How To Choose The Right EOH Braking System
Overview: Electric over hydraulic brake systems blend electric control with hydraulic pressure to deliver strong, stable braking for trailers that require reliable stopping power under various loads. When evaluating options, consider compatibility, durability, installation, and maintenance requirements to ensure optimal performance across seasons and terrains.
- Output Pressure (PSI): Most suitable for 1–3 axle trailers. Common ratings are 1500–1600 PSI. Ensure your drum or disc brakes are designed to handle the chosen PSI without over-pressurization.
- Brake Type Compatibility: Disc brakes generally perform well with EOH systems. Confirm that the actuator is listed as compatible with your brake type and vehicle configuration.
- Environmental Durability: Marine-grade seals, anodized housings, and weatherproof casings extend life in sun, rain, and salt spray. Consider corrosion protection for coastal environments.
- Wiring and Controls: A four-wire connector is common (power, brake signal, ground, and switch/auxiliary). Verify compatibility with your existing trailer brake controller and vehicle electrical system.
- Mounting and Footprint: Check dimensions, mounting style, and trailer frame clearance. Some actuators include integrated reservoirs or sealed tanks for fluid reserves, reducing maintenance visits.
- Maintenance Needs: Look for sealed systems with minimal moving parts and easy access to the reservoir. Regularly inspect for leaks and monitor fluid levels, especially in harsh climates.
- Warranty and Support: Choose brands with established dealer networks and accessible support. This helps with troubleshooting and parts replacement over the trailer’s lifespan.
Bottom line: For trailers carrying boats, RVs, livestock, or equipment, selecting an EOH actuator with a 1600 PSI rating and robust sealing typically yields consistent braking performance in diverse environments. Prioritize models with proven marine or weather-resistant design, straightforward wiring, and compatibility with your brake discs or drums.
