Dexter BrakeRite Electric Over Hydraulic Actuator
The Dexter BrakeRite EO H actuator delivers rapid response for hydraulic disc brakes and is rated at 1,500 psi. It is designed specifically for hydraulic disc brake applications, enabling integrated electronic control with hydraulic actuation. The unit’s compact design supports straightforward retrofits and compatibility with many standard brake controls. Consider this option when you need strong hydraulic pressure with an electric control signal for precise stopping power.
Dexter K71-651-00 Electric/Hydraulic Actuator 1600 PSI
Dexter’s K71-651-00 combines electric and hydraulic actuation with a 1,600 psi rating, suitable for hydraulic disc brake setups. This actuator is designed for robust performance, offering compatibility with common brake controls and dependable operation in trailer braking systems. It is a practical choice for trailers needing higher pressure output and reliable conversion from electric signals to hydraulic braking force.
Deutsche Hydrapro Alpha G1600
The Alpha G1600 offers a 1,600 psi hydraulic output with a high-quality DC motor and a sealed fluid reservoir. Its independently sealed fluid tank provides extra reserves, and the weatherproof, anodized alloy casing helps protect components from the elements. This model is well-suited for exposed trailer environments where durability and reliability under varied conditions are priorities.
Hydrastar HBA-10 Electric/Hydraulic Drum Actuator
Hydrastar’s HBA-10 is designed for drum brake applications with electric/hydraulic control and a 1,000 psi rating. It is compatible with single or tandem axle trailers that utilize drum brakes and requires an in-cabin electric brake controller (sold separately). This option is ideal for users transitioning from standard drum brakes to an electric over hydraulic setup while maintaining drum braking systems.
SOUTHWEST WHEEL MAXX KIT
The MAXX KIT from SOUTHWEST WHEEL combines an 8705101 Demco Disc Brake Actuator with a DeeMaxx single-axle brake hose kit and Gold Zinc calipers. This package delivers a complete hydraulic disc brake actuation solution with robust hardware suitable for single-axle setups. It provides a high-capacity surge and reliable braking response, suitable for upgrading or retrofitting disc brake systems on trailers.
Buying Guide: Key Purchase Considerations
- Pressure rating and brake type: Match the actuator’s psi rating to your trailer’s disc or drum brake requirements. Higher psi models are typically used for disc brake systems that demand stronger hydraulic force.
- Electrical control compatibility: Ensure the actuator is compatible with your trailer’s brake controller and wiring harness. Some models require specific controllers or wiring configurations.
- Environmental durability: For exposed trailers, look for weatherproof enclosures and corrosion-resistant materials (e.g., anodized housings, sealed reservoirs).
- Installation and retrofit complexity: Consider how easy it is to retrofit into your existing brake system, including mounting, hose routing, and calibration steps.
- Warranty and support: A longer warranty often reflects build quality and manufacturer support, which can be important for trailer systems exposed to road conditions.
- Application type: Distinguish between drum vs. disc brake actuators. Disc brake systems generally require higher performance actuators, while drum systems may work with different hydraulic configurations.
- Maintenance requirements: Check fluid reservoir design, seal integrity, and ease of pump servicing to minimize downtime and maintenance costs.
- Brand ecosystem and availability: Consider dealer support, compatibility with existing accessories, and the ease of sourcing replacement parts when needed.
This selection covers a range of common trailer braking needs—from high-performance disc brake actuation to drum brake compatibility and complete kit solutions—allowing you to choose an actuator that aligns with your system’s specifications, climate, and installation constraints.
