Key Features
- Genuine OEM Braking Integrity — Built to DEMCO DA-91 specification, ensuring the actuator delivers the correct hydraulic surge response for safe, controlled trailer braking.
- Direct-Mount Replacement — Engineered to install directly into the existing actuator housing on compatible Water Trailer and pump trailer configurations without fabrication or adapter hardware.
- Broad Multiquip Fitment — Confirmed for Water Trailer models WT5C, WTE5C, WT5HP, WTE5HP, concrete pump LS300GK, and trash pump models MQ600H, MQ600HTB, MQ600HTP, and additional LS and Mayco pump series.
- Hydraulic Surge Activation — Responds to trailer-to-tow-vehicle deceleration forces to automatically engage trailer brakes, keeping braking proportional and predictable under load.
- Critical Safety Component — The brake actuator is a primary safety device on towed equipment; a worn or failed unit can result in loss of trailer braking, making correct OEM replacement essential for compliant, safe operation.
A brake actuator is the mechanical heart of a hydraulic surge braking system on a towed trailer. When the tow vehicle decelerates, inertia pushes the trailer tongue forward into the actuator, compressing a hydraulic cylinder that applies the trailer's wheel brakes in proportion to the stopping force. Without a properly functioning actuator, trailer braking becomes inconsistent or fails entirely, creating a serious safety hazard — particularly on heavy water trailers and pump units operating on uneven job sites. Replacing a worn or damaged actuator with the correct DEMCO DA-91 unit restores full braking response and keeps towed equipment operating safely and legally.
