2014 Shorelander 19ft trailer with surge disc brakes

[Bruggar709]

Having trouble bleeding my trailer brakes, tried holding up on the release tab and pumping pressure through the small hole next to the release tab. It doesn't seem to move any fluid? What am I doing wrong?

I connected my truck, chocked the trailer wheels, and instructed my friend to forward/reverse into the chocks while I open/close the bleeder screw. Start from the driver side because its further away, then to the passenger side, then back to the driver side to be sure that there's no air bubbles. I was getting tons of pressure towards the end and the fluid was shooting 10ft out the bleeder screw. Wear dirty clothes.

I bought a good set of wheel chocks and used the method above by myself. Chock front and back of a wheel, back up and hold the brake, then set emergency brake. Go back and loosen bleeder, then tighten. Go back to truck and pull forward, then back, then forward, then back again. Hold brake, set emergency brake, and open bleeder. I used tubing from the bleeder nipple, drilled a hole and water bottle cap, put tubing in water bottle filled with brake fluid to monitor the fluid and air bubbles. I needed to get rusty, water/brake fluid out of the lines. Swapped it out a couple of times so I could tell if I was getting clean fluid through. Monitor the master cylinder as it doesn't hold very much fluid.
