Hydraulic brake actuators control & engage hydraulic disc, and drum brakes. They are available in a variety of sizes and configurations to fit larger and smaller trailers. Hydraulic brake actuators, sometimes referred to as surge brakes are popular in the marine and rental industries.

DEMCO BRAKE ACTUATORS
DEMCO BRAKE ACTUATORS
Demco hydraulic brake actuators are specifically designed to perform even in the harshest braking environments. The master cylinder cap has an automotive-style diaphragm for a completely enclosed brake system, preventing brake fluid contamination. Master cylinder pushrod is covered by a rubber boot for additional dirt and moisture protection. DA66 & DA9150 actuators utilize heavy-duty self lubricating rollers, DA10 & DA20 use UHMW nylon wear pads, totally eliminating the potential for roller “freeze-up”. Common repair parts are interchangeable between models, minimizing the need for large service parts inventory.

The actuator applies the trailer brakes automatically with proportional force when the tow vehicles brakes are applied. It is simple to install and operate, and also offers breakaway protection. A brake line kit is also needed to complete the system.
