Dexter Titan Model 20 Disc Brake Actuator
Heavy-duty 20,000 lb GVWR surge actuator for hydraulic disc brake systems, featuring a zinc-plated finish and integrated reversing solenoid.
Overview
The Dexter Titan Model 20 is a surge-style hydraulic actuator built for heavy-duty trailer disc brake applications. Rated for 20,000 lb GVWR with a 2,000 lb tongue load, this zinc-plated unit is designed for strength, corrosion resistance, and long service life. It includes a built-in reversing solenoid to prevent brake engagement while backing and an extended housing cover to help protect hydraulic components.
R&P Service Insight
Heavy-duty disc brake actuators work in a demanding environment where load, weather, and repeated braking all matter.
- Wear: Sliding and hydraulic components can lose responsiveness after repeated braking cycles.
- Exposure: Zinc plating helps resist corrosion in harsh road and marine-adjacent conditions.
- Load: Higher-capacity trailers place real stress on the coupler body and master cylinder assembly.
R&P Knowledge Hub
Compatibility: Designed for surge-style hydraulic disc brake systems using a 2-5/16" hitch ball connection.
Vehicle / System Fit: Built for heavy-duty trailers up to 20,000 lbs GVWR with a 3" wide straight tongue frame.
Installation Notes: Verify your frame width is 3" and confirm your mounting pattern matches the 3" and 5" front-to-back hole spacing before ordering.
Performance Insight: The extended housing helps shield the reversing solenoid and brake line connection area from road debris and impact exposure.
R&P Repair Insight
Before installing a replacement actuator, confirm the full coupler and brake setup matches your trailer’s actual configuration.
- Frame Check: Confirm a 3" tongue width and correct mounting hole spacing.
- Brake System Check: This actuator is for hydraulic disc brake applications, not every hydraulic drum setup.
- Wiring Check: The reversing solenoid must be wired correctly to the tow vehicle’s reverse circuit for proper backing function.
