Since the trailer was off of the ground it would not take much voltage to stop the wheels from spinning so they may be getting power but they may not be getting enough power due to a short or wiring issue. But 9 times out of 10 weak trailer brakes…

Although there are standard bearing and seal combinations, sometimes (especially on older trailers) the "correct" seal won't fit, as you have found out. The closest seal that we have to the 1.654 Inner Diameter (ID) that you…

The 168255TC oil seal is designed for use on for oil bath hubs, but they can be used on grease hubs. They basically just provide a better seal to hold oil in; they will still work for grease. The springs on your oil seals are required to function…

I called Lippert and they informed me of the grease seal dimensions for your 3,500 lb axle. The correct replacement grease seal for you is part #168255TB.

Hey Stephen, yes the replacement trailer brake magnet part #AKBRKR-M12 that you referenced is the correct replacement magnet for the brake assemblies #AKEBRK-7-SA.

Assuming that when you tested the resistance of the brakes you were testing the two wires on each magnet and getting 2.0 and 2.8 ohms the magnets on your trailer are not working correctly and will need to be replaced. For 7" brakes you should…

The Demco Hydraulic Brake Actuator part #DM72VR is a great option to replace an Atwood 82543. That said, it does not come with any sort of reverse lockout feature therefore in order to reverse without the brakes locking up you will either need to add…

Your existing Atwood model 83010 Brake Actuator (which as you mentioned is no longer available) is an 8,000 pound rated assembly for hydraulic drum brakes that's compatible with a 2" ball. It's designed to fit 3" wide straight…

The distance between the mounting holes of the Dexter coupler part #DX56FR is 3 inches so it would bolt right up to your trailer. For a manual lockout you could use with this you'd want part #DX94FR. Standard brake line kits like the part #DM5424…

Dexter recommends a SAE 90, SAE 80W-90 or SAE 75W-90 oil to be used. I recommend the Kodiak Synthetic Bearing Oil for Oil Bath Hubs #XLPROLUBE as it is a synthetic 90 weight oil that helps reduce friction and to keep bearings cool. Since your cap was…

Really the only way to tell if you have manual or self-adjusting brakes is to remove the hub and take a look inside. If you can see a cable running at an angle (see included photo), then you have self adjusting brakes like the Electric Trailer Brake…

I would check the magnets for wear before going on to test them with a meter. If the magnets show abnormal wear or if you can see the windings beginning to show through the friction surface of the magnet then they will need to be replaced. To further…
