I've got a leak on my surge brakes, I believe coming from the actuator inside the hub. Haven't torn it apart yet to see for sure. The trailer is 22 years old so I'm sure once I tear into it, I'm going to end up replacing more then just the actuator. Has anyone converted there trailer? If so, what kind of cost am I looking at? I'm handy with that kind of stuff so I would be doing it myself. It's a single axel that is original to the 96 charger 186.
