Load Rite 8,500lb Disc Brake Actuator Tie Down Engineering Model

The Model 850E Disc Brake Actuator from Tie Down Engineering is engineered to provide seamless brake synchronization between your boat trailer and tow vehicle. Designed for marine enthusiasts, this actuator ensures reliable braking performance, enhancing safety and control during your boating adventures.

How It Functions

The Model 850E utilizes the surge or push motion of the trailer toward the tow vehicle to automatically synchronize the trailer brakes with the tow vehicle's axle brakes. When your trailer exerts pressure on the tow vehicle, the actuator telescopes, transferring force to the master cylinder and generating the necessary hydraulic pressure for effective braking. The integrated dampening shock absorber reduces shock impact against the hitch ball, providing a smooth and stable towing experience.

Installation Guidelines

Prior to installing the Model 850E Actuator, refer to your tow vehicle’s owner’s manual for towing capacity and specific recommendations. Ensure compliance with your state’s braking regulations, as brake laws often set minimum standards. Depending on your needs, you might consider adding extra brakes to your boat trailer for enhanced safety.

The Model 850E comes fully assembled and is ready to bolt onto tongue sizes of 3”x3”, 3”x4”, and 3”x5”. Make sure all connections are secure, and follow the installation instructions provided in the owner's manual.
