Brake Lockout Cap for Dexter / UFP Actuator 250-031973

Reverse Lockout Actuator Cap

The Brake Lockout Cap for Dexter/UFP Actuator 250-031973 is a replacement reverse lockout cap used on compatible EZ Loader boat trailers with Dexter / UFP hydraulic surge brake actuators. This EZ Loader brake lockout cap helps temporarily prevent the surge brakes from fully engaging while backing the trailer when used correctly.

This cap is made by Dexter and is used with compatible UFP Model A-60, A-75, and XR-84 actuators with a 7,500 lb rating. It is commonly used on EZ Loader boat trailers with hydraulic surge brake systems, including many disc-brake trailer applications.

The center position is used for normal trailer operation. Turning the cap right allows the trailer to back up by locking out brake action. Turning the cap left removes the cap for inspection or service.

This is not a brake pad, caliper, rotor, or actuator replacement. It is a reverse lockout cap for the actuator. Proper fitment matters because the cap must match the actuator model, top-mount lockout style, actuator rating, and existing Dexter / UFP brake actuator setup.

Typical EZ Loader Trailer Applications

This lockout cap is commonly used on compatible EZ Loader boat trailers equipped with Dexter / UFP hydraulic surge brake actuators. It is designed for UFP Model A-60, A-75, and XR-84 actuators with a 7,500 lb rating.

It is most often used when backing the trailer in situations where the surge brake actuator would otherwise apply brake pressure, such as backing over soft ground, up an incline, or into a ramp area.

How the Lockout Cap Works

• Center position: normal trailer operation
• Turn right: allows trailer backup by locking out the brake action
• Turn left: removes the cap for inspection or service

The cap should be reset for normal trailer operation before towing. Always confirm proper brake function after service or adjustment.

Installation Considerations

Before replacing the brake lockout cap, inspect the actuator area and confirm the trailer uses the correct Dexter / UFP top-lockout actuator setup. A damaged cap, worn actuator, incorrect actuator model, or mismatched lockout style can affect operation.

• Confirm the actuator model before ordering.
• Verify the actuator is a compatible UFP A-60, A-75, or XR-84 7,500 lb model.
• Check that your actuator uses the top-mount lockout cap style.
• Inspect the actuator, brake lines, and brake fluid level as part of brake system service.
• Do not rely on this cap to correct an actuator, brake line, or brake system failure.

Fitment Guidance

This is not a universal brake actuator cap. Correct fitment depends on the trailer model, actuator model, actuator rating, top-lockout cap style, hydraulic brake system, and existing actuator configuration.

• Confirm part number 250-031973 when possible.
• Check the actuator model: A-60, A-75, or XR-84.
• Confirm the 7,500 lb actuator rating.
• Compare the existing cap diameter and top-lockout design.
• Send photos of the actuator and cap area if you are unsure about fitment.

Real-World Insight

A reverse lockout cap can be very helpful when backing a surge-brake trailer, especially on an incline, soft ground, or ramp approach. However, it is not a substitute for a properly working actuator and brake system. If the trailer brakes drag, lock up, or fail to release during normal towing, inspect the actuator, brake fluid, brake lines, and brake components before assuming the cap is the only issue.
