2004 Tahoe swing tounge trailer - need new surge actuator

[fish hook]

The master cylinder is leaking like a sieve on my trailer and the dealership is telling me a replacement is no longer available. My thought is to replace the entire actuator along with the master cylinder but I don't know which style to look at. The trailer is single axle with disc brakes. Anyone done this?

first, identify the brand of actuator (post a pic if you dont know)

then most likely there is a simply MC repair kit avaiable.

most likely is a UFP actuator and rebuild kits and new actuators are available.

If you can't find the parts then the bolt patterns are often standard for a replacement actuator.
You might have to fuss around with fittings a bit.

Actuator model is Tie Down Model 70LC based on the sticker on the tongue. I have researched this but do not find this number anywhere and the folks at one of the major trailer parts stores hasn't heard of that number either. The Model 70LP looks exactly like my master cylinder, and I'm wondering if this is the replacement I need.
