Replacement Master Cylinder for UFP Disc Brake Actuators
The UFP Disc Brake Master Cylinder 7500 / 16000 - 250-031975 is a replacement hydraulic master cylinder used on compatible EZ Loader boat trailers with UFP disc brake actuator systems. This EZ Loader master cylinder is designed for disc brake applications and is listed for UFP actuator setups in the 7,500 lb and 16,000 lb actuator family.
The master cylinder is one of the most important internal components inside a hydraulic surge brake actuator. When the actuator compresses during braking, the master cylinder creates hydraulic pressure and sends brake fluid through the trailer brake lines to the disc brake calipers.
This part is used as an actuator repair component. It may help restore proper hydraulic brake pressure when the original master cylinder is leaking, worn, sticking, bypassing internally, corroded, or no longer building proper pressure.
This is not a complete brake actuator, coupler, caliper, rotor, or brake line. It is a replacement master cylinder for compatible UFP disc brake actuator assemblies. Correct fitment depends on the actuator model, brake type, actuator rating, mounting style, push rod/piston configuration, brake line outlet, and original EZ Loader trailer brake setup.

Typical EZ Loader Trailer Applications
This master cylinder is commonly used on compatible EZ Loader boat trailers equipped with UFP hydraulic surge brake actuators for disc brake systems. It is listed for UFP disc brake actuator applications in the 7,500 lb and 16,000 lb actuator family.
Always compare the part number, actuator model, brake type, actuator rating, master cylinder body, outlet connection, push rod/piston setup, and trailer VIN before ordering.
Why This Master Cylinder Matters
The master cylinder creates the hydraulic pressure that operates the trailer brakes. If the master cylinder is leaking, internally bypassing, corroded, sticking, or unable to build pressure, the trailer brakes may feel weak, delayed, uneven, or may not work correctly.
Installation Considerations
- Confirm the trailer uses a compatible UFP disc brake actuator before ordering.
- Confirm this is the disc brake master cylinder version, not a drum brake master cylinder version.
- Compare the existing master cylinder body, outlet, and push rod/piston setup.
- Inspect the actuator housing, shock/damper, reverse lockout components, brake lines, and brake fluid condition during service.
- Replace contaminated or old brake fluid as needed.
- Bleed the hydraulic brake system after master cylinder replacement.
- After service, test the trailer brakes in a safe area before normal towing.
Fitment Guidance
This is not a universal master cylinder. Correct fitment depends on the actuator model, disc brake setup, actuator rating, master cylinder shape, push rod/piston configuration, outlet connection, and original trailer brake system.
- Confirm part number 250-031975 when possible.
- Confirm the actuator is a UFP disc brake actuator.
- Confirm the actuator rating family: 7,500 lb / 16,000 lb, as applicable.
- Compare the old master cylinder to the new part before ordering.
- Check the outlet connection and internal actuator components.
- Send photos if you are unsure about fitment.

Real-World Insight
A failed master cylinder can make a trailer brake system feel weak even when the brake lines, calipers, and rotors appear serviceable. Before replacing the entire actuator, inspect the master cylinder, actuator shock/damper, brake fluid, reverse lockout components, and hydraulic brake lines. If the actuator housing and related components are still serviceable, replacing the master cylinder may be the correct repair path.
