Features to know about

Rust and Corrosion Are No Match: Zinc-Plated Steel Construction

If you're towing in marine environments or any wet conditions, the zinc-plated steel construction of the Demco Hydraulic Trailer Brake Actuator is an absolute game-changer. Its 500-hour salt spray rating means it’s built to withstand even the harshest elements, keeping your brakes reliable and your trailer rust-free.

Seamless Brake Activation Every Time: Surge-Type Hydraulic Actuator

No more worries about brake lag! The surge-type hydraulic actuator efficiently activates your trailer’s brakes as soon as your tow vehicle decelerates. This ensures smooth and seamless braking, making every stop safe and controlled, perfect for any trailer up to 8,000 lbs.

Handle Different Couplers with Ease: Adjustable Channel Settings

Switching trailers or needing a custom setup? The actuator’s adjustable channel has three mounting positions, allowing you to easily fit different coupler attachments. It offers the adaptability you need without the hassle, keeping your towing dynamic and stress-free.

Keep Your Brake Fluid Clean: Automotive-Style Diaphragm Cap

The automotive-style diaphragm cap on the master cylinder efficiently prevents fluid contamination, ensuring your hydraulic actuator operates smoothly. This thoughtful addition is all about maintaining system integrity and enhancing performance over the long haul.

Reliable and Strong Towing: Heavy-Duty Bolt-On Installation

For those who value durability, the heavy-duty steel construction combined with a bolt-on installation makes sure your actuator stays firmly in place. It's a reliable partner for your trailer, promising stability and strength during every journey.

Kate F and her team at etrailer have been most helpful in completing our order and with follow up to make sure we were satisfied. Great attention to detail and excellent to work with.



by:

Fit perfectly onto my Genie TZ 50 Manlift. The only difference is the position of the mounting channel for the Ball Receiver. The top of the old one was nearly flush with the top of the horizontal channel. I had the Ball Receiver in the bottom two holes and when I put the Receiver in the bottom two holes of the new one it made the Lift Tongue approximately 2-1/2" lower. Might have to get a higher Ball Mount for the truck. Not a deal breaker.



by:

Product as described. Fits well. Works well. At a reasonable price. Packaging a little shaky though. I will use etrailer again and recommend to others.
