Have a 2011 Shorelander trailer and i'm getting ready to replace springs, hubs/rotors, bearings and calipers. I bought OE UFP DB-35 calipers and they came pre-assembled with pads. Are there any adjustments that need to be made or just attach the brake lines and bleed them? Also, they're sold as "universal" fit but one does not have the dual port banjo fitting to line the other caliper. Can I just remove the old fitting and swap it?
