Dexter Marine Products Surge Brake Actuator Inner Member for Disc Brakes

The Dexter Marine Products surge brake actuator inner member for disc brakes is a replacement hydraulic surge actuator component for trailer disc brake systems. It slides into a compatible outer housing. It supplies the coupler, master cylinder and actuator components that make up a surge brake actuator, sometimes called a surge coupler. Replacing the inner member is a practical way to restore smooth, dependable braking on boat trailers.

Key Features:

• Hydraulic surge operation: The actuator applies the trailer brakes when the trailer pushes toward the tow vehicle. This needs no electrical brake controller in the tow vehicle.
• Linear stroke design: It is designed to give even brake line pressure through the stroke, which supports smooth stopping and less chucking.
• Aluminum master cylinder: Aluminum is used instead of plastic or steel for strength and corrosion resistance.
• Sealed reservoir: A diaphragm barrier helps keep moisture out of the brake fluid. It also helps keep fluid from escaping and damaging trailer paint.
• Interchangeable design: UFP-style inner members are made to match compatible outer housings, which keeps replacement straightforward.
• Disc brake configuration: Built for hydraulic disc brake trailer systems, including marine and boat trailer use.

Dexter is a long-established trailer axle and brake manufacturer. This inner member is a genuine replacement part for UFP-style surge actuators and is offered in several capacity and axle configurations.
