My 31' Soveriegn has disc brakes on it. I can't seem to make them work. I have a prodigy controller in the truck and it is putting out voltage on the correct port on the pigtail.
I played with the pigtail port on the TT while figuring out the pigtail wiring and I can put 12v
on the brakes pin and I hear something click over on the tongue of the TT. I took the cover off and I can see a master cylinder of some sort and it looks like an old booster down below it. I have no idea how this supposed to work.
I really don't know where to start. I'm attaching a pic, can anyone give me a brief rundown on how this system works and how I can test it/ fix it? Thanks in advance,
