Bleeding brakes on boat trailer

Have to replace a caliper on my Shorelandr trailer. Wondering how do you bleed the brake lines. Specifically, what is the best/safest method to apply pressure to the brake system.

Not sure what system you own, but here is a link to the manual for the one I own.

Also, this YouTube is pretty good.

I had to do the same thing, I used a tie down on the tong and a wrench with a bucket with a little piece of rubber hose and the caliper and did it myself. Pretty straight forward.

Thanks guys, the video was great. Same system I have so it looks like a fairly straight forward process now.

that works well,and so does this,on airplanes,the bleeder screw is on the bottom of the caliper,yes,its upside down! we drain the brake master and using an oil can that is dedicated for this purpose,we fill the oil can with hydraulic oil for planes,brake fluid for vehicles,using a small hose to connect the oil can to the bleeder screw,open the bleeder and pump the fluid backwards up to the master cylinder,once you see clear fluid coming into the master,quit and go the other side,this works very well for bleeding hydraulic clutch systems also,makes it a one man job,I have been doing it this way for years and never had a problem,the reason this works is because it is dang hard to get an air bubble to go down stream,much easier to push it up hill.hope this helps!!
