UFP Complete Disc Brake Actuator with Atwood Mounting Holes – K9907528
Upgrade or replace your trailer’s surge brake system with the UFP K9907528 complete disc brake actuator. Engineered for disc brake trailer applications, this actuator delivers smooth, responsive braking performance through a corrosion-resistant aluminum master cylinder tuned specifically for disc brake output pressure.
The industry-standard lever lock latch features a hole at the top of the ball socket for a quick visual confirmation that the ball is fully seated before towing — a simple but important safety feature. The inner member is fully removable for straightforward repair or replacement without replacing the entire unit. Mounting holes are spaced to fit Atwood coupler configurations, making this a direct-fit replacement for trailers originally equipped with Atwood hardware.

Parts Desk Insights
This is the actuator to order when you need a complete, ready-to-install disc brake surge unit that fits an existing Atwood coupler mounting pattern — a common configuration on many North American boat and utility trailers. The disc brake-tuned master cylinder is an important detail: using a drum brake actuator on a disc brake system (or vice versa) will result in incorrect output pressure and poor braking performance, so confirm your trailer uses disc brakes before ordering. The removable inner member is a genuine serviceability advantage — if the master cylinder or inner components wear over time, you can replace just that assembly rather than the entire actuator. The visual ball-seated indicator at the top of the latch is a practical safety feature worth using every time you hitch up.
