DOT 3 or DOT 4 brake fluid is recommended for Demco brake actuators like the # DM72VR. You should never use DOT 5 as it will wear out seals very quickly.

The Adapter Port #DE73MR you found is an exact replacement for the one on the Caliper #DE86VR. This is designed to accept a brake line like the Kodiak #bh-3mfs90ff-1-5 and not a banjo type connection. You are going to have to alter your brake lines…

You need to measure the inside portion of your hub drum. You need the width and depth like in the picture I attached. I can almost guarantee that you have 10 inch assemblies based on the 4 bolt mounting pattern though. So for free backing assemblies…

DOT5 brake fluid is what you'd want to use in the Dexter surge actuator part #DX89FR. If the breakaway pin was pulled it would be replaceable. The breakaway cable is replaceable.

When you bleed the brakes on your trailer after installing the Kodiak Calipers #KDBC225DAC, you will want to start with the brake that is furthest away from the actuator. Of the two bleeder valves, you will want to use the bleeder valve that is on…

The best option would be to go with Disc Brakes #DE66YR. These are the best option as they repel water better than other trailer brakes and will offer superior braking. This will require the Zinc-Plated Brake Actuator #T47457107K and Brake Line Kit…

Thank you for providing that information. According to ShoreLandr your current hub uses #L44649 inner and outer bearings. That means you can use the Trailer Idler Hub Assembly for 2K Axles - 13" to 15" Wheels - 5 on 4-1/2 - Pre-Greased…

Based off the measurements you provided, you've got a #84 spindle, so the correct bearings are the #L44649 and #L68149, and #RG06-050 grease seals. We typically try to put bearing numbers of popular manufacturers on the bearing pages but those…
