Review of etrailer Trailer Hubs and Drums - Pre Greased Hub with Integrated Drum - AKHD-555-35-EZ-K Video

To determine the size of the brake assemblies you need you have to measure the depth and width of the hub drum on the axle like what you see in the picture I attached. The most common size is 2-1/4 inch wide like the #T4071600-500 that you…

To determine the correct magnet you will need, you need to go by the manufacturer and size of the brakes on the trailer. Sometimes, the year of the brakes is needed as well. The brakes may have information stamped into the metal on the back side…

If the brake magnet is worn to the point that the windings are visible then you know it's time to replace the magnet. However, magnets can also fail without the visible signs of wear. Check out the FAQ article I attached on testing brake…

The Electric Trailer Brake Kit #AKEBRK-35-SA has a square 4 bolt mounting pattern with the bolts spread 2-13/16" both vertically and horizontally. I have included an image with these measurements.

The right and left orientation is determined if you are standing behind the trailer looking towards the tow vehicle. The left side is the drivers side and the right side is the passengers side. Tthe shorter brake pad will always be in the front of…

You said you checked the brake magnets. When inspecting them did you notice if the windings inside the magnets are showing? If so this is most likely the reason that the short is showing up on the controller when the vehicle is moving. This would…

You can measure either the outer diameter of the part of the dust cap that fits into the hub OR the inner diameter of the hub where the dust cap goes using calipers such as #PTW80157. Calipers are needed because the measurement has to be as accurate…
