So when I got home today from using the boat, backed into garage and when I went to put down the wheel lift I noticed the handle was coated in fluid. My first thought was how did the hydraulic fluid leak out and get onto the handle. But i put it down and saw it was holding pressure so figured I would continue on. I got to the hitch lock and noticed that had fluid on it (jack is on drivers side, lock is passenger side). At that point I started to look under my truck to see if something blew out. Didn't see anything so raised the tongue off the ball and noticed that the trailer tongue, the brake slot was only about half way forward, looked a little dirty like maybe it was sticking. When I looked back a couple moments later though it had released forward. So after putting the boat away I swung open the tongue, took a look around and under and really didn't see anything obvious. I did notice for sure though that there is fluid spots all down both sides of my trailer to about the I series light plate (about 8 feet back). My assumption if anything is it must be in the brake master or whatever its called up front (I know not much about trailer brakes). But what I don't see anywhere is the fluid release point, if that much came out I feel like I should see it someplace. I will clean it and check it out tomorrow, but if anyone has ideas or experience I am open to ideas.
Trailer is a 2019, tandem axle, disc brakes, vault hubs I believe they are called. Its fairly new to me but has been trouble free, and didn't notice anything odd pulling it home today.
